How viable is Solar in Canada given its weather? (I am ignorant about it and only know that it's really cold and cloudy most of the time).

Alberta is one of the best locales for solar on the continent -- it's sunny most of the year -- and had an exploding renewables sector.

Until the far right O&G lobbyist provincial government kneecapped the sector.

Cold is fine - solar panels perform better the lower the temperature.

That's what makes Calgary ideal for solar.

A city like Calgary gets 233 days of sunny days a year. All across the prairies there is plenty of days filled with sun. British Columbia would probably not be great (like Seattle) but they could probably generate wind and hydro.
Its not so much the days but the hours. Days start getting pretty short in winter. The sun also doesn't get as high in the sky so the efficiency of a fixed panel drops further.
Calgary is quite sunny at 2400 hrs/year.

But not nearly as much as Vegas (3800) or LA (3250) or SF (2950).
