Ontario Power Generation planning to extend life of aging Pickering Nuclear Generating Station by decades

Ontario Power Generation is moving ahead with a plan to extend the life of the aging Pickering Nuclear Generating Station by decades, as the province tries to secure more electricity supply in the face of increasing demand.

Nuclear big player in getting to Net Zero

“Our province still needs this station and its workers,” he said at a press conference outside the nuclear plant. The construction phase will create about 11,000 jobs, he said, and provide about 6,000 jobs for decades.

OPG plans to spend $2 billion on engineering and design work and securing key components for the project that is expected to be completed in the mid-2030s.

Neither Smith nor OPG officials would give an estimate for how much the entire refurbishment will cost.

“It would be irresponsible at this point in time to put a number out there, because it’s this essential design and scoping and engineering work that is going to get us to the place where we can have a number,” Smith said.

OPG said a refurbishment at its Darlington Nuclear Generating Station is costing $12.8 billion and is on time and on budget.

Ken Hartwick, chief executive of OPG, said the Darlington refurbishment as well as one at Bruce Power will help guide the Pickering life extension.

“We have learned a lot about what it takes to refurbish a nuclear station the right way with thousands of lessons learned from Darlington and Bruce Power that we will apply to Pickering,” Hartwick said.

The four units produce about 2,000 megawatts of electricity, enough to power two million homes.

The Independent Electricity System Operator has said Ontario’s electricity demand is expected to grow by about two per cent each year,  but could be even higher. A promise to build 1.5 million homes by 2031 and several large-scale manufacturing investments such as electric vehicle battery plants are helping to push demand higher.

The province needs more supply particularly starting in the mid-2030s, the IESO has said.

Keith Stewart, a senior energy strategist with Greenpeace Canada, said the price of wind and solar power with battery storage has “dropped like a stone” and should be more central to Ontario’s energy policy.

“Any credible independent cost-benefit analysis would find that we should be investing in the renewable-powered energy system of the future, rather than pouring billions more into rebuilding nuclear reactors long past their best-before date,” he wrote in a statement.

Pickering produces about 14 per cent of the province’s electricity but its current licence to operate the four units in question expires at the end of this year. OPG has asked the Canadian Nuclear Safety Commission to extend that to 2026, but a public hearing for that application has not yet been scheduled.

Green Party Leader Mike Schreiner said Greens understand that nuclear power will continue to be part of the energy mix for decades, but the province also needs much more wind and solar power and no more natural gas generation.

“Instead of attracting jobs and investment in low-cost renewables, the Ford government is making Ontario’s grid dirtier and more expensive by prioritizing dirty fossil gas plants and the costly, poor-performing Pickering plant,” he wrote in a statement.

The IESO announced last month that it is looking to add 2,000 megawatts of non-emitting electricity generation online such as wind, solar, bioenergy and hydro to the system. However, it also says natural gas is still required to ensure supply and stability in the short to medium term, though it will also increase greenhouse-gas emissions from the electricity sector.

Ontario’s electricity system was 94 per cent emissions free in 2020, but today that figure has fallen to 90 per cent.

The nuclear safety commission would still have to approve the Pickering refurbishment.

Two other units at Pickering are also set to stop operating at the end of this year. They are part of what’s known as the A units, which came online in the 1970s and were removed from service in 1997. Two of the units were refurbished and began operating again in 2003 and 2005.

Canada’s debate on energy levelled up in 2025

Published on

From Resource Works

By

Compared to last December, Canadians are paying far more attention.

Canada’s energy conversation has changed in a year, not by becoming gentler, but by becoming real. In late 2024, pipelines were still treated as symbols, and most people tuned out. By December 2025, Canadians are arguing about tolls, tariffs, tanker law, carbon pricing, and Indigenous equity in the same breath, because those details now ultimately decide what gets built and what stays in the binder. Prime Minister Mark Carney has gone from a green bureaucrat to an ostensible backer of another pipeline from Alberta to the West Coast.

From hypothetical to live instrument

The pivot began when the Trans Mountain expansion started operating in May 2024, tripling capacity from Alberta to the B.C. coast. The project’s C$34 billion price tag, and the question of who absorbs the overrun, forced a more adult debate than the old slogans ever allowed. With more barrels moving and new Asian cargoes becoming routine, the line stopped being hypothetical and became a live economic instrument, complete with uncomfortable arithmetic about costs, revenues, and taxpayer exposure.

The American election cycle then poured gasoline on the discussion. Talk in Washington about resurrecting Keystone XL, alongside President-elect Donald Trump’s threats of 25 percent tariffs, reminded Canadians how quickly market access can be turned into leverage.

In that context, Trans Mountain is being discussed not just as infrastructure, but as an emergency outlet if U.S. refiners start pricing in new levies.

The world keeps building

Against that backdrop, the world kept building. Global pipeline planning has not paused for Canadian anxieties, with more than 233,000 kilometres of large diameter oil and gas lines announced or advancing for 2024 to 2030. The claim that blocking Canadian projects keeps fossil fuels in the ground sounds thinner when other jurisdictions are plainly racing ahead.

The biggest shift, though, is domestic. Ottawa and Alberta signed a memorandum of understanding in late November 2025 that sketches conditions for a potential new oil pipeline to the West Coast, alongside a strengthened industrial carbon price and a Pathways Alliance carbon capture requirement. One Financial Post column argued the northwest coast fight may be a diversion, because cheaper capacity additions are on the table. Another argued the MOU is effectively a set of investment killers, because tanker ban changes, Indigenous co ownership, B.C. engagement, and CCUS preconditions create multiple points of failure.

This is where Margareta Dovgal deserves credit. Writing about the Commons vote where Conservatives tabled a motion echoing the Liberals’ own MOU language, she captured the new mood. Canadians are no longer impressed by politicians who talk like builders and vote like blockers. Symbolic yeses and procedural noes are now obvious, and voters are keeping score.

Skills for a new era

The same sharper attention is landing on carbon capture, once a technocratic sidebar. Under the MOU, a new bitumen corridor is tied to Pathways Alliance scale carbon management, and that linkage is already shaping labour planning. A Calgary based training initiative backed by federal funding aims to prepare more than 1,000 workers for carbon capture and storage roles, a sign that contested policy is producing concrete demand for skills.

British Columbia is no longer watching from the bleachers. It flared again at Carney’s December 18 virtual meeting, after Environment Minister Steven Guilbeault resigned from cabinet over it. Premier David Eby has attacked the Alberta Ottawa agreement as unacceptable, and Prime Minister Mark Carney has been forced into talks with premiers amid trade uncertainty. Polling suggests the public mood is shifting, too, with a slim majority of Canadians, and of British Columbians, saying they would support a new Alberta to West Coast pipeline even if the B.C. government opposed it, and similar support for lifting the tanker ban.

None of this guarantees a new line, or even an expanded one. But compared with last year’s tired trench warfare, the argument now has stakes, participants, and facts. Canadians have woken up to the reality that energy policy is not a culture war accessory. It is industrial policy, trade policy, and national unity policy, all at once.

New Poll Shows Ontarians See Oil & Gas as Key to Jobs, Economy, and Trade

Published on

From Canada Action

By Cody Battershill 

A new Ontario-wide survey conducted by Nanos Research on behalf of Canada Action finds strong public consensus that Canadian oil and gas revenues are critical to jobs, economic growth, and trade – and that Canada should lean into its energy advantage at home and abroad.

“Our polling feedback shows that a majority of Ontarians recognize the vital, irreplaceable role oil and gas has to play in our national economy. Canadians are telling us they want to see more support for the oil and gas sector, which is foundational to our standard of living and economy at large,” said Canada Action spokesperson, Cody Battershill.

The online survey of 1,000 Ontarians shows that more than four in five (84 per cent) respondents believe oil and gas revenues are important for creating jobs for Canadians and building a stronger economy. Additionally, four-in-five (80 per cent) support Canada developing a strategy to become a preferred oil supplier to countries, while Ontarians are more than eight times as likely to support as to oppose Canada supplying oil and gas, provided it remains a major source of energy worldwide.

POLL - more than four in five (84 per cent) of Ontarians believe oil and gas revenues are important for creating jobs for Canadians

“Building new trade infrastructure, including pipelines to the coasts that would get our oil and gas resources to international markets, can help Canadians diversify our trading partners, maximize the value of our resources, and secure a strong and prosperous future for our families,” Battershill said.

Also, nearly four-in-five (79 per cent) of Ontarians say oil and gas revenues are important for keeping energy costs manageable for Canadians.

“Our poll is just one of many in Canada since the start of 2025 that show a majority of Canadians are supportive of oil and gas development. It’s time we get moving forward on these projects without delay and learn from the lessons of our past, where we saw multiple pipelines cancelled to the detriment of Canada’s long-term economic success.”

80 per cent of Ontarians support Canada developing a strategy to become a preferred oil supplier to the world

Additional findings include:

  • Four-in-five (80 per cent) of Ontarians support Canada supplying oil and gas, provided it remains a major source of energy worldwide.
  • Four-in five (80 per cent) of Ontarians believe oil and gas revenues are important when it comes to building stronger trading partnerships.
  • Nearly four-in-five (79 per cent) of Ontarians say oil and gas revenues are important for keeping energy costs manageable for Canadians.
  • Nearly four-in-five (78 per cent) of Ontarians support Canada stepping up to provide our key NATO allies with secure energy sources.
  • Nearly four-in-five (78 per cent) of Ontarians support Canada increasing oil and gas exports around the world, about six and a half times more likely than to oppose.
  • Nearly four-in-five (77 per cent) of Ontarians support Canada providing Asia and Europe with oil and gas so that they are less reliant on authoritarian suppliers.
  • Nearly three-in-four (74 per cent) of Ontarians support Canada increasing oil and gas exports around the world, five times more likely than to oppose.
  • Nearly three-in-four (74 per cent) of Ontarians say oil and gas revenues are important to reducing taxes for Canadians.
  • More than seven-in-ten (71 per cent) of Ontarians support building new energy infrastructure projects without reducing environmental protections and safety.
  • More than six-in-ten (63 per cent) of Canadians say they are important for paying for social programs, including health care, education, and other public services.
  • Respondents were nine times more likely to say the government approval process for energy infrastructure projects is too slow (46 per cent) rather than too fast (5 per cent).

80 per cent of Ontarians support Canada supplying oil and gas to the world as long as it continues to be a major source of energy79 per cent of Ontarians say oil and gas revenues are important for keeping energy costs manageable for Canadians78 per cent of Ontarians support Canada stepping up to provide our key NATO allies with secure energy sources78 per cent of Ontarians support increasing oil and gas exports around the world, 6x more than those who oppose this

About the survey

The survey was conducted by Nanos Research for Canada Action using a representative non-probability online panel of 1,000 Ontarians aged 18 and older between December 10 and 12, 2025.

While a margin of error cannot be calculated for non-probability samples, a probability sample of 1,000 respondents would have a margin of error of ±3.1 percentage points, 19 times out of 20.
