Heron Bay mayor resigns after suspension for insulting councillors
Normand Pelletier tells residents in northern N.B. municipality he didn't make decision lightly
Tension on Heron Bay council has led to the resignation of the mayor, Normand Pelletier, not long after he served a suspension for insulting three councillors over a proposed mine.
Pelletier announced his resignation Monday on social media.
In a page-long letter, Pelletier said the "decision was not made lightly," and serving for the past 10 years as mayor of Dalhousie and then Heron Bay was one of his "greatest honours."
The new municipality was formed in 2023 with the amalgamation of Dalhousie and Charlo.
But council nerves have been strained in recent months, especially because of a proposal to turn a quarry within municipal boundaries into an open pozzolan mine. Pozzolan is billed as a low-carbon alternative to cement.
The mine is still in the environmental impact study phase, with the company behind it, EcoRock Dalhousie, holding monthly steering committee meetings to get feedback.
Pelletier has told CBC News multiple times on the record that he was neither for nor against the proposed mine.
Heron Bay council hopes to rebuild trust after mayor resignsBut in May, he was suspended for 40 days after telling a business publication, the Logic, that three councillors who opposed the project "didn't have a f--king clue what they were doing."
When he returned to the job in July, Pelletier said, he found that council had moved its chambers from the first floor of city hall to the second without consulting him.
"This … has been the last drop that made the glass overflow," he said in his resignation letter.
Deputy mayor steps up
Deputy Mayor Denis McIntyre now takes over Pelletier's duties as mayor.
"[It was] a bit of a surprise, but I kind of understand his decision and it's an accumulation of things that happened," McIntyre said.

McIntyre will remain in the position until May 2026, when municipal elections will be held in Heron Bay and across the province.
In the meantime, he said, he hopes to rebuild residents' trust in council.
"Communication is a big thing" McIntyre said. "We have a good council. We're going to make sure that we work together and answer all the questions that the citizens wanted."
Residents react
News of Pelletier's departure from council travelled quickly on Monday morning and brought mixe reactions from residents.
"I'm happy for him," Chantelle Robichaud said. "I think at one point our lives, we have to decide where we want to place our priorities. Well wishes in his future endeavours and lots of quality time with his family, and let's see what newness we can bring to our community."
"If he wants to quit, let him quit," said resident Robert Worster. "We'll get somebody better to replace him."
David Guitard of Eel River Crossing said he wasn't aware of the resignation but didn't agree with what Pelletier had said about his colleagues.
"That's completely wrong to do in the first place," he said. "I've got my own opinion about the open pit mine, but I wouldn't call anybody down for anything."

resignation letter suggests a last straw for him was that during his
suspension, council relocated its chambers without consulting him. (Charles-Étienne Drouin/Radio Canada)
Dalhousie resident Pauline Diotte, a vocal opponent of the mine, said it played a big role in the fallout on council.
"We were quite happy with our little town, and then the mines came in and it destroyed us. It divided us," said Diotte, who is a representative on the steering committee for the mine.
Diotte said she personally has attended several council meetings and has seen how Pelletier treated some of his colleagues.
"Normand had his own way of being at these meetings, being aggressive and wanting his way," she said.
But Diotte, who hopes to run for council in the next election, said there's no bad blood, adding, "Normand was a good guy. It's just not a good mayor, that's all."
Charlo resident Carlos Doucet, who works for Levesque & McIntyre Electric Co. is also on the steering committee as a representative of the business community. He said he's neutral on the mine question, and was disappointed to hear of Pelletier's resignation.
"I met Norm a couple of times. He's a good individual, and I think he was doing some really good things for the region.
"He had to let go because the pressure from the other side was coming into him, and he had too much, and he had to enjoy his life now. So I wish him all the best."

Mine expansion would give Dalhousie community a 'black eye,' residents fear
Mine expansion would give Dalhousie community a 'black eye,' residents fear
Company behind pozzolan mine says project is in 'conceptual' stage, but it has already bought land
Hundreds of residents of Heron Bay in northern New Brunswick are worried about plans to turn a quarry into a massive mining operation within municipal boundaries just 200 metres from a school.
It was standing room only at two public meetings recently as people asked a mining company questions such as: "Does this create dust … that would spread in the bay or in the town of Dalhousie?" and "Have you ever thought about the people who have wells up there?"
Quebec-based companies Carboniq Inc. and Cimbec Canada Inc. have come together to form EcoRock, which hopes to greatly expand a quarry already in the Dalhousie community into an open mine.
The material being extracted is pozzolan, a low-carbon alternative to the cement now used in the creation of concrete. The company's goal is to process the material at a local plant, then export it around the world, using the nearby port and rail lines.

expansion. (Victoria Walton/CBC)
With a population of about 3,000, Dalhousie amalgamated with nearby Charlo in 2023 to form Heron Bay.
The community has faced economic hardship in recent years after the closure of three major industries — a paper mill, a chemical plant and a power generating station.
Francis Forlini, the EcoRock Dalhousie general manager, said the project would create up to 168 permanent jobs.
Proposed mine expansion raises tension in northern N.B. community
"We're really at the start of the project," he said. "Right now the project is very conceptual."
Pozzolan is a 400-million-year-old volcanic ash now being considered as a way to lower emissions in the production of the binder needed for concrete. For the cement now being used, a mixture of limestone and clay goes into a kiln, where it decomposes under high heat. The process produces greenhouse gas emissions, but with pozzolan, this step is avoided.
EcoRock has purchased the quarry and surrounding land, along with the West Wharf and nearby railway.

million years ago, Sugarloaf Mountain in nearby Campbellton was a
volcano. (Alexandre Silberman/CBC)
Forlini said he believes the expansion of the quarry could see the amount of pozzolan extracted go from 55,000 tonnes each year to three million tonnes.
"Maybe in December or November 2025, maybe sooner if everything goes really, really well, maybe later if it takes longer," he said.
"So it's really hard to say, but we're in no rush. We want to do things right to make sure that we become a good neighbour."
Never zoned for a mine
Federal and provincial approvals will be needed at different stages of the project.
At the municipal level, Heron Bay Mayor Norman Pelletier said the existing rock quarry has operated as a non-conforming use within Dalhousie town boundaries but an expansion can't move ahead without the area being rezoned.
The Heron Bay municipality recently passed first reading of a zoning bylaw amendment that would give it the authority to allow, deny or put stipulations on a mine or quarry in the area. Pelletier voted to break the tie vote of 3-3. Council decided to delay the second and third reading until 2025.
"It gives us a voice," Pelletier said. "We could say that the company who wants to establish a mine in our town, you're going to have to follow all the criteria."
"We as a municipality can say, well, you're not going to be driving on our roads with your trucks. We want a conveyor system, we want silos. We don't want no dust."
EcoRock said the next steps include a feasibility study and an environmental impact study on top of the environmental "survey" that's already been completed.
Pelletier, who's also the provincial Progressive Conservative candidate in Restigouche East, has not yet decided whether to support the mine.
"There's still a lot of obstacles in the way. I'm not going to say yes or no until we hear all the facts," Pelletier said.
"I'm pro whatever development's going to come to our region. I'm not going to deny that. But I want to see the whole package laid out in front of me."

election candidate, hasn't made up his mind about the project. (Victoria Walton/CBC)
If the mine does expand, it would go from its current 11 hectares to 80 hectares.
EcoRock promised residents at meetings that the mine would be buffered by 200 metres of forest on all sides, and the popular Dalhousie Mountain Trail would be a "conservation" site.
Concerns about dredging the ocean floor to allow for ships to load pozzolan at West Wharf were also raised.

the proposed size of the mine after expansion, marked with a dotted
yellow line. The federal government says on its website that the
expanded mine could mean 168 permanent jobs. (EcoRock Dalhousie)
Across the Bay of Chaleur, Miguasha, Que., resident Jean-Marc Beaulieu worried the expansion would hurt his community.
"The bottom of the bay is heavily polluted," he said. "And with the mine, if they dredge the port or they dredge the bay to get bigger ships to the port, they will just put back all this sediment that are contaminated in circulation."
David (Tapit) Slagger, a member of Woodstock First Nation who lives in Dalhousie, said he too worries the project could harm the Bay of Chaleur and its inhabitants.
"What they're proposing here is going to affect our way of life, the fishery and, and overall the environment," he said. "The reverberations of blasting would have a devastating effect on the fishery."
Residents fear for environment
None of the residents who asked questions at the recent meetings spoke in favour of the project, and many signs along Victoria Road, which leads to the area, reflect opposition to the project.

Que., resident Jean-Mark Beaulieu says he can often hear loud cars or
boats on the Dalhousie side of the Chaleur Bay and worries about the
noise levels and pollution if the mine expands. (Victoria Walton/CBC)
"We want to turn the page on industry," said resident Gail Fearon, who served on Dalhousie's town council for more than a decade, until 2022.
She worries the company isn't consulting enough with the community.
"You see [the company] moving ahead and going 100 per cent with this project, and getting the rail lines and getting the ports put in place and everything. And we haven't even dealt with the bylaw."
Gail Fearon says she wants to see Dalhousie move beyond its industrial past. (Victoria Walton/CBC)
Slagger wants to see the community lean into tourism, instead of returning to its industrial past.
"It's going to hurt the town and the people, the tourism industry, it will give Dalhousie such a black eye that no one will want to come here," he said.

developers have completed a geological analysis of core samples
extracted from the existing quarry in Dalhousie. They expect to have a
detailed plan for the project by the end of the year. (Michael Heenan/CBC)
Fearon said there's now a group of over 1,500 residents from both sides of the bay, and surrounding areas, who are opposed to the mine expansion.
And as for whether the company behind the project can convince her it's a good idea?
"Not in my lifetime, no."

Proposed volcanic-rock mine divides northern New Brunswick town
Proposed volcanic-rock mine divides northern New Brunswick town
Some Dalhousie residents welcome prospect of jobs, others fear environmental impact
Two
Quebec-based companies hope to turn this existing quarry into a large
mine near Dalhousie in northern New Brunswick. The area is home to a
vast deposit of pozzolan, a volcanic rock that can be used by the cement
industry to lower emissions. (Michael Heenan/CBC)In a vast quarry on New Brunswick's north shore, Réjean Carrier looks up at towering walls of ashen-grey rock, cut deep into the landscape.
"We have this presence of volcanic ashes in a zone around Dalhousie," he explains in French, pointing out a rock called pozzolan. "It will bring good jobs to the area."
Carrier, president of Quebec-based Carboniq Inc., hopes to turn an existing quarry into an open mine to extract the material as a low-carbon alternative for the cement industry.
His vision is to take the pozzolan from a small mountain, process it at a plant in the area, and export it globally using nearby port and rail lines.
Could a volcanic-rock mine change life in northern New Brunswick?
The existing rock quarry has operated as a non-conforming use within Dalhousie town boundaries but is much smaller than the project Carboniq imagines.
In the community of Dalhousie, the prospect of a new mine is raising questions over how to balance the economic benefits with potential impacts on the environment.
The community has faced economic struggles in recent years, struggling to reinvent itself after the loss of three major industries. The closure of a paper mill, a chemical plant and a power generation station has led to shuttered businesses and a declining population.
The idea of a new mine is being embraced by some residents, with talk of hundreds of jobs during construction and as many as 168 once the processing plant is in operation. But others fear an open pit mine, near a school and residential areas, could impact their quality of life and harm the environment.

convert into a mine for the cement industry. 'It will bring good jobs to
the area,' he said. (Alexandre Silberman/CBC)
Mayor Normand Pelletier said residents have lots of questions and the developers will have to make their case to the community. He said people are divided on the issue.
"We have a lot of people that are interested and would like to see a project as such take place," he said. "For one, it's going to create good-paying jobs.
"We're kind of anxious to hear the company and how they're going to promote it and make those public consultations to ease the pressure on the citizens."
Volcanic rock
The natural resource is the result of the region's prehistoric past. Four hundred million years ago, Sugarloaf Mountain in nearby Campbellton was a volcano. As it spewed ash across the landscape, it created layers of pozzolan rock.
At the Dalhousie site, studies have revealed the deposit of rock is deep enough to last at least 100 years, according to the developers.
Pozzolan is now being looked at as a potential solution to drastically lower emissions in cement manufacturing. In current mixtures, limestone is added to a kiln and decomposes under high heat, which produces greenhouse gas emissions. But with pozzolan, that step in the process is avoided entirely.

The material is currently being extracted at some sites in the western United States and around the Mediterranean Sea.
The project has received backing from the federal government. In 2022, the Atlantic Canada Opportunities Agency made a conditionally repayable contribution of $1.2 million to cover geological and environmental surveys.
Carrier is working on the project with Guy Rousseau, president of cement company Cimbec Canada. The pair launched their venture in 2022.

Carrier said the geological analysis of the deposit has been completed and the project is now focused on how pozzolan might need to be processed to meet the needs of the industry. The rock is being tested in a laboratory.
"The demand will increase because we're searching for products to decarbonize the production of cement," he said.
'It's going to leave a scar in the landscape'
The municipality of Heron Bay held a public meeting last month to discuss new zoning, including changes that would allow quarries and mines to operate in parts of the community of Dalhousie.
Residents filled the room to question councillors about the project, raising concerns about noise, dust, truck traffic and pollution. Many demanded more information about the mine, questioning why they haven't heard directly from the developers.
Gail Fearon, who spoke at the meeting, said she wants to see greater transparency so her community can make an informed decision.
"My problem is yes it's jobs, but a job at what expense?" she said in an interview, overlooking post-industrial brownfields on the community's waterfront.

Fearon, a former town councillor, spoke at a recent meeting about
proposed zoning changes to allow quarries and mines to operate in the
community. She said residents need more transparency to be able to make
an informed decision about the project. (Alexandre Silberman/CBC)
Fearon said the project could lead to a permanent impact on the environment and the potential consequences need to be seriously considered. Growing up in the community, she remembers seeing waste from the paper plant being released into the bay.
"The industries that left, they left at least a flat piece of property. Whereas this project, it's going to leave a scar in the landscape," she said.
Carrier said he is listening to residents and recognizes some have questions and concerns. But he said it's too early to bring plans to the public for feedback. The project is still in a planning stage.

from the existing quarry in Dalhousie. They expect to have a detailed

"We don't want to design a project in public, but we are taking these concerns into account, from an environmental survey, a social acceptance survey," he said.
Carrier said a walking trail near the top of Dalhousie Mountain will not be affected, since the geological deposit stops well before that point in the landscape. He said possible impacts to neighbours could be controlled and mitigated.
"We're making the plan taking into account the different constraints imposed, that citizens impose, the environment imposes, laws impose," he said.

Corporations exist to earn shareholders money.
(By law), corporations are beholden to their shareholders. Not "the environment", the collective, or feelings.
I'm not the one getting hysterical about how "environmentally friendly" (just) green energy projects are.
BTW: the most common liberal mentality to developing our resources is fake "conservativism" which involved giving tax pay dollars to "private" businesses, rather than letting the free market work.
It's not real conservatism - it's an attack on it while wearing a disguise.

Year over year increases in total GDP do not necessarily translate to an increase in rate of growth in GDP/capita.
In the above time span, the rate of growth in GDP/capita was only on the increase in 2010, 2016, 2017 and 2021.
Furthermore, our GDP per capita (inflation adjusted) has grown by only 1.9% since the current federal government took office in 2015. During the same period, for comparison's sake, the United States growth has been a whopping 8 times higher.
And, looking ahead, from now to 2030 Canada is projected to have the slowest rate of GDP per capita growth among the 38 developed countries in the OECD.
Simply put, our economy is stalling relative to past performance and all other comparable countries around the world.
It's time to stop pretending that all is well.
Your socialist leanings are quite obvious, and you need to realize that there are (thank goodness) many who disagree with you.

Government of Canada supports a net‑zero industry transformation
News release
November 8, 2022 · Dalhousie, New Brunswick · Atlantic Canada Opportunities Agency
By investing in strategic projects that leverage regional assets and target greenhouse gas (GHG) reduction, we can create a healthier environment and new economic opportunities. This will foster a strong, sustainable recovery and build a greener economy for all Canadians. The Government of Canada is investing to help Carboniq Inc. and Cimbec Canada Inc., the codevelopers of the Dalhousie Pozzolan project, conduct studies to produce a cementitious material to help decarbonize the cement industry, which is alone responsible for 7%–8% of global greenhouse gas emissions.
Diversifying for the future
Today, René Arseneault, Member of Parliament for Madawaska‑Restigouche, announced a conditionally repayable contribution of $1,223,361 to Carboniq Inc. and Cimbec Canada Inc. as part of the Canada Coal Transition Initiative – Infrastructure Fund. The announcement was made on behalf of the Honourable Ginette Petitpas Taylor, Minister of Official Languages and Minister responsible for ACOA.
This investment will help Carboniq Inc. and Cimbec Canada Inc. complete the initial steps of a project to extract a natural pozzolan deposit, a rock of volcanic origin. These steps include assessing deposit size and quality and conducting environmental surveys in the work area in preparation for a future environmental impact study. The extraction and processing of this pozzolan have the potential to create up to 500 jobs during the construction phase, as well as 168 permanent jobs once the processing plant is in operation.
Dalhousie’s natural pozzolan deposit, the result of an accumulation of volcanic ashes over 400 million years ago, may play a significant role in reducing the carbon footprint of cement manufacturers by providing a material that does not need to be calcined to offer cementitious properties.
This project must be completed before any major mining developments can take place. The codevelopers also recognize the importance of engaging in dialogue with First Nations for any subsequent projects.
Today’s announcement further demonstrates the Government of Canada’s commitment to focus on economic diversification to ensure the creation of good jobs and wealth, both now and for the future.

pozzolana
pozzolana, hydraulic cement perfected by the Romans and still used in some countries, traditionally made by grinding a material of volcanic origin (the pozzolan) with powdered hydrated lime. Roman engineers used two parts by weight of pozzolan mixed with one part of lime to give strength to mortar and concrete in bridges and other masonry and brickwork. During the 3rd century bce the Romans used pozzolana instead of sand in concrete and mortared rubblework, giving extraordinary strength. Used with an aggregate of broken tuff, travertine, brick, or marble, the material contributed to the evolution of new architectural forms in such monumental constructions as the Pantheon and the Baths of Caracalla at Rome.
Pozzolana was first found at Puteoli (modern Pozzuoli), near Naples, where there are still extensive beds, and also around Rome. Natural pozzolana is often composed mainly of a fine chocolate-red volcanic earth. Industrial, artificial pozzolans are produced in furnaces where organic materials, such as coal, are burned and the ash is reclaimed. Fly ash is the most common form of industrial pozzolan.

PROJECT PRESENTATION
Dalhousie Pozzolan
WHAT IS POZZOLAN?
Dalhousie pozzolan is a rock made of volcanic ash ejected about 400 million years ago by the active volcano of Mount Sugarloaf. This rock can partially replace a substance used in the production of cement called “clinker” (calcined limestone). It would only need to be finely ground.
Purpose of the project
The objective of the project is to provide the cement industry with a very low carbon footprint cementitious material that will reduce the clinker-cement ratio and thus reduce the need for clinker, the production of which is the source of significant greenhouse gas (GHG) emissions.
When limestone is heated in a cement plant kiln, its decomposition under the effect of the heat leads to the production of carbon dioxide (CO2). Since the ground pozzolan does not need to be heated, all emissions related to the decomposition of the limestone as well as those related to the use of fossil fuels for heat production will be avoided.
The Dalhousie Pozzolan Project has the potential to reduce GHG emissions from the Canadian cement industry by up to 3 million tons per year. That's the equivalent of taking 1 million medium-sized cars off the road every year.
A large deposit and the necessary infrastructure
There is a large deposit of pozzolan at the project site in Dalhousie.
In addition, all the necessary infrastructure for the project is already in place: the quarry, the railway, a high voltage power line, and the port.
Benefits for individuals and communities
The project would bring several benefits to the community:
-
The project would create jobs, both directly and indirectly.
-
A royalty would be paid to the municipality
-
The municipal taxes on the site would increase, providing additional revenue to the municipality.
-
Infrastructure that was no longer in use would be revitalized.
-
We would also like to develop a partnership with the Ugpi’ganjig First Nation.
A project in 2 phases
The quarry
A quarry is already operating on the site. It has been there since 1932. For the first two years, the plan would be to continue operating this quarry and sell the construction stone.
These operations would be the same as those currently taking place at the quarry.
Meanwhile, a feasibility study on the extraction of pozzolan would be conducted. This study would include an environmental impact assessment.
Phase 1
Phase 2
The pozzolan mine
If the project is approved, pozzolan extraction would begin. The project's classification would change, and the quarry would become a mine.
Provisional timeline
Pozzolan production: a simple process
To produce pozzolan, we would take the stone from the quarry and grind it more finely.
Even the rejected stone that is unsuitable for construction could be processed in this way. Because of this, there would be no waste. Everything extracted from the quarry would be used.
Valuable dust that would be captured
The rock would be ground in a closed building since we would want to minimize the amount of dust released into the air as much as possible, for two reasons:
-
To comply with regulations and promote good relations with the community.
-
To capture and sell the dust as a product.
Few new infrastructures to build
New infrastructures would be needed at the port to load the ships.
To transport the products from the quarry to the port, a few scenarios are possible. These scenarios will be evaluated in the environmental impact study.
Quarry expansion and creation of a conservation area
Currently, the quarry’s production is 55,000 tons per year. By 2027, the goal would be to reach a production of 3 million tons per year, including:
• 2 million tons per year of pozzolan
• 1 million tons per year of construction aggregates
To do this, the quarry would need to be expanded. A conservation area would also be created.
On the map, the solid yellow rectangle represents the current approximate area of the quarry. The dotted yellow line represents the projected expansion. The purple rectangle represents the conservation area.
Please note:
-
The land within the conservation area (in purple) would be protected.
-
The project would not touch the hiking trail on the mountain (Dalhousie Mountain Peak Trail). There would be 200 m of wooded area between the quarry and the trail.
-
There would also be 200 m of wooded area between the quarry and the École Aux Quatre Vents.
-
The project would not create any new industrial sites.

A crucial step : studying the project’s environmental impacts
An
environmental assessment will need to be conducted to understand the
potential impacts of the project on air, water, wildlife, vegetation,
and the local population.
We are also preparing a proposal for a citizen consultation process.
This would involve meetings and activities that would allow people who
live in the area to actively contribute to the environmental assessment
and determine the conditions under which the project could move forward.
