A battle over jurisdictional authority continued to heat up Wednesday, as federal Environment Minister Steven Guilbeault insisted an element of Alberta's pushback to Ottawa's oil and gas cap could land companies in hot water.

Representatives of Alberta’s oil and gas sector say the provincial government did not consult with their industry before announcing plans to take to challenge the proposed federal greenhouse gas emissions cap.

The Alberta government is using its signature sovereignty act to again push back against Ottawa’s planned emissions cap amid mounting concerns about the potential impact of heavy cross-border tariffs proposed by U.

Alberta Premier Danielle Smith says her government is looking to challenge the proposed federal greenhouse gas emissions cap, including by passing legislation to give the province exclusive authority over emissions data and banning federal employees from designated oil and gas sites.
