From $1,500,000 the minimum is 20% and the loan cannot be insured. On top of the down payment, set aside a separate amount for closing costs: welcome tax, notary, inspection and adjustments. How much depends on the property and the municipality; ask me for an estimate for your case at pre-approval.
