Not even close.

I’d say expenses are 50% higher (Toronto to SF, mostly housing), but income is 100-200% higher.

Are we talking about the same Canada? Besides food, almost everything else is more expensive in Canada, diapers cost twice as much for example.

Not so much! Vancouver isn't cheap either, and a lot of stuff in the US is just cheaper.

And whenever I'm making more than I'm spending, I'd happily multiply both numbers.

Cost of living has been skyrocketing in Toronto and Vancouver as well unfortunately.
