A 25% export tariff on electricity from the Canadian province of Ontario – slated to take effect Monday – could raise prices for New York consumers and increase greenhouse gas emissions in the process, energy experts say.

Following President Trump’s delay on North American tariffs, Ontario Premier Doug Ford announced a 25% tariff on electricity exports to New York, Michigan, and Minnesota. While New York sources about 5% of its electricity from Canada, experts say immediate price hikes are unlikely.

As Ontario Premier Doug Ford plans on a 25% tariff on electricity exports, one state lawmaker says power supply will not be affected. However, bill rates can be spared from raises if the state does something about where it gets power.
