Still plenty of sun in southern Canada to make enough power for your house. The payback isn’t based on latitude so much as it is local power cost. Granted, latitude matters eventually, like in northern Canada. But wind would be an excellent alternative in that case.
Several decades? Is this hypothetical house inside a cave? Sounds more like anti-renewable energy propaganda.
In Australia, it takes between about 3-7 years to break even on the total cost of a system. Not close to several decades.
not propaganda, just southern canada and a decade out of date.

Still sounds questionable. E.g. the chart here for Canadian solar (https://kuby.ca/solar/solar-information/articles/the-cost-of-solar-panels) shows that you hit a relative break even point at 9-10 years on a $15k system. And a complete break even at under 20 years.
That sounds well under several decades to me.
