No clue on what the actual price would be here, just that there is a BYD model in China that has a ~300 km range that sells for around $14k CAD. Once you add various safety certifications etc, I'd expect that price to at least double, but that's still cheaper than all but the most budget ICE offerings.
As for infrastructure, that's complicated. I assume the distribution network could be matched to demand fairly quickly, but the supply side could get interesting. Still, most of the EV owners I know charge overnight when there's surplus power, so maybe it doesn't have as big an impact as expected. It's certainly more viable in Canada than most countries with our plentiful hydro generation options.
As for road tax, that would probably have to get built into licensing fees to make sure it was a user fee rather than a tax on all electricity. Either way, it's something we're already paying one way or another. If it wasn't already tied to US mega corps selling gas at obscene profits, it might be less painful.
In other words, to me, all surmountable problems. You trade some issues for others, and longer trips would be more complicated, but in the end it would add up to a more independent Canada than we have now, at least from an energy perspective. If we kept or processed our own oil, that might make the math different, but we don't, so it doesn't. If nothing else, it would go a long way to decoupling our economy from the US, which comes with even more pros and potential cons that far exceed this thread...
