CALGARY — Alberta Premier Danielle Smith and Ontario Premier Doug Ford used a Calgary energy gathering Monday to press for a proposed pipeline that could eventually carry up to 800,000 barrels of Alberta oil a day to Ontario.The premiers spoke alongside business and energy leaders at Enserva’s 2026 Speaker Series at the TELUS Convention Centre. Their discussion focused on the infrastructure and provincial cooperation needed to move Canadian energy to domestic and overseas markets.Ford pointed to the Northern Shield Energy Corridor, a proposed route from Hardisty, Alberta, to Sarnia, Ontario. The Government of Ontario says the project would initially move an estimated 500,000 barrels of oil a day, with capacity that could expand to 800,000 barrels. .ANALYSIS: Ford and Smith's pipeline proposal has a Manitoba problem.“Working with partners like Premier Smith, we’re building the critical Canadian energy infrastructure that will provide secure, reliable and affordable energy for Canadian families and businesses so that we can protect Canadian sovereignty,” Ford said in a press release.Smith said Alberta is ready to supply more energy if it can reach new markets.“By building the infrastructure we need to reach new markets, we can attract spending, create jobs and unlock even more opportunity across the country,” she said.“Alberta and Ontario have a strong partnership, and when our provinces work together to grow our economies, all of Canada benefits.”Enserva CEO Gurpreet Lail said changing trade relationships and concerns about energy security have increased the pressure on governments and industry to act.“Canada has the resources, expertise and workforce to be a global energy leader, but we need to turn that potential into action,” Lail said.The Northern Shield corridor remains a proposal.Ontario and Alberta unveiled its proposed route in July as part of their efforts to strengthen domestic energy supply and open export markets.
