What is normal? It's hard for middle class people to afford normal housing stock in highly advanced countries without 30 years of amortizing debt. Yes, I understand that some countries force you to chain bullet mortgages over ~30 years to achieve a similar effect.
I think you're conflating mortgage term (which is typically 5 years fixed or variable in Canada) and amortization. The latter can go up to 25 years for CMHC-insured loans at the time.
