Actually 15A breakers are standard throughout Canada and the US. Housewiring is only rated for 15A, so 20A breakers are not permitted.

Sort of not true and sort of true. A 20 AMP breaker is allowed you just have to have the bigger gauge wire to allow for it. So switching a 15 to a 20 is not permitted because the wiring as Bob stated is "most likely" rated for 15 amps.
