South of us, that's because of who has been occupying the White House for four years leading up to a few months ago. California (free to set their own emission standards) is going it alone:
Governor Newsom Announces California Will Phase Out Gasoline-Powered Cars & Drastically Reduce Demand for Fossil Fuel in California’s Fight Against Climate Change | California Governor
Quite a few other states duplicate California's emission standards.
There's no point selling one set of vehicles for half of the USA and another set of vehicles for the other half, although it wouldn't surprise me if that happens temporarily for a short period.
Quebec:
Quebec to ban sale of new gasoline-powered cars from 2035
British Columbia:
British Columbia passes emissions law banning sale of gas-powered cars by 2040
The practical reality is that auto manufacturers are all planning to switch over to electric for everything light-duty by somewhere in the 2030 to 2040 timeframe. Many of them have stated that they are stopping development on new combustion engines (i.e. whatever engines and powertrains that they have in production now, will be the ones they leave in production until the end). It's pretty likely that by the late 2020s, no new combustion-engine vehicles will be introduced to market (whatever's in production at that time, may carry over until the end of production)
We're already seeing the high-end, aspirational vehicles are making the switch.
It will work out fine.
