I would beg to differ in your characterization of this bill with regard to provincial powers.
I have here a quote from Premier Andrew Furey: “Newfoundland and Labrador is perfectly positioned in the green energy transition. Part of that transition requires offshore wind so our province can become a world leader in green hydrogen. We continue to support the Government of Canada on Bill C-49”. That doesn't seem to me like we're forcing someone to do something.
I have another quote from Premier Tim Houston.
