So what, you'd say we have "the cheapest cell service in the world" if we took our currency and reissued it with 1000 pre-2020 dollar equaling 1 post-2020 dollar [0]?
Electronics cost the same amount regardless of what currency you buy them in, which is at least a good portion of the cost of running a cell company. Wages are also similar in the US and Canada.
The Canadian GDP per person is slightly greater than the American GDP per person after we convert everything to the same asset (e.g. USD) [1]. So it's not like we are poorer than americans and we need to adjust for that. It just happens to be the case that a loonie is less than a dollar bill, and a toonie more than a dollar bill.
[0] There is precedent for doing this, though not in Canada, typically it is done after hyper inflation to make amounts of currency seem more reasonable.
Absolutely not. We aren't importing data from the US. You can't tie exchange rate to CoL.
