Two calculators built on the rules that apply here: mortgages compounded semi-annually, CMHC insurance premiums added to the loan, land transfer tax charged twice in Toronto, and a principal residence that pays no capital gains tax when a portfolio would. Free, no sign-in, nothing stored.
Not "is the mortgage cheaper than the rent" — if you liquidated today, which path leaves you holding more? Counts the cost of getting in and out, invests the down payment on the renting side, and taxes the portfolio but not the house. Tells you the year one overtakes the other, which is really the question.
Payment, full schedule, the balance you renew at when the term ends, and what every payment frequency actually costs. Accelerated bi-weekly is a prepayment dressed as a schedule, and on a typical mortgage it is worth tens of thousands — so it is priced here rather than buried.
A Canadian fixed rate is compounded twice a year, not monthly. Use the American formula and the payment comes out about $20 a month high on a $700,000 mortgage, every month, for 25 years.
Under 20% down the premium is 2.80–4.50% of the loan and is added to the mortgage — you borrow it and pay interest on it. In Ontario, Quebec and Saskatchewan the sales tax on it is due in cash at closing.
The largest closing cost in most of the country, and charged by both the province and the city in Toronto and Montreal. First-time buyer rebates are applied where they apply.
A home's gain is tax-free; a non-registered portfolio's is not. A rent-vs-buy that ignores this is quietly arguing for renting, so the account the renter invests in is an input here.
Five-year term, twenty-five-year amortization. Only the term's rate is known, so the balance you renew at is shown as its own number rather than hidden in a total.
