For homes under $500,000, the minimum is 5%. Between $500,000 and $999,999, it is 5% on the first $500,000 and 10% on the rest. Properties of $1 million or more require at least 20% down.
CMHC mortgage default insurance is required when your down payment is under 20%. This calculator estimates the premium and adds it to your mortgage balance, which raises your monthly payment slightly.
