Special Mortgage Programs at Canada’s Big Banks: Which One Is Right for You
STEP, FlexLine, Homeline — fancy names, but what are they really, and how do you choose?
How do the big Canadian banks’ mortgage programs differ, and how should I choose?
The big banks’ core difference is their ‘readvanceable’ products and added flexibility. Scotia’s STEP, TD’s Home Equity FlexLine, RBC’s Homeline, BMO’s ReadiLine, and CIBC’s Home Power all bundle a mortgage with a line of credit (HELOC) that grows as you pay down principal — borrowing up to 80% of home value (the revolving portion capped at 65%). Beyond rate, weigh flexibility, the prepayment-penalty (IRD) calculation, and whether you go through a bank or a broker channel (like First National or MCAP, often lower-rate but broker-only).

Clients constantly ask me: ‘What’s actually different between the big banks’ mortgages — do I just pick whoever has the lowest rate?’ Rate matters, but it’s the tip of the iceberg. Each bank’s flagship product has its own logic, and the penalty calculation, the flexibility, and the ability to borrow as you repay matter more over time than a 0.1% rate gap. This article lays out the main programs and the rules behind them so you’re not steered by a sales pitch.

Core concept: what ‘readvanceable’ means
Nearly all the big banks’ flagship products work the same way: a mortgage bundled with a HELOC line of credit in one plan, where every dollar of principal you repay raises the credit you can borrow. The total ceiling is 80% of home value, with the revolving (HELOC) portion capped at 65%. The upside is flexibility — repaid principal can be re-borrowed for investing or renovations; the risk is that all that flexibility makes over-borrowing easy.

Bank vs broker channel (First National, MCAP)
💡 Whichever you pick, the stress test is a hard rule you can’t dodge. Per OSFI (updated January 2026), an uninsured-mortgage borrower must qualify at the greater of the contract rate + 2% or 5.25%. In other words, whether and how much you can borrow depends not on the rate you actually pay but on this higher ‘qualifying rate.’ Estimate your affordability against that standard before you shop.
The 2024 insured-mortgage reforms favour first-time buyers
Per the Department of Finance Canada, reforms effective December 15, 2024: the insured-mortgage price cap rose from $1M to $1.5M, and 30-year amortizations were extended to all first-time buyers and all buyers of new builds. The down-payment rule is 5% on the first $500K and 10% on the $500K–$1.5M portion. This lowers the entry barrier and monthly burden for first-time buyers.
How to choose: don’t fixate on rate
Frequently Asked Questions
Is the bank with the lowest rate always the best deal?
Not necessarily. Rate matters, but the prepayment-penalty (IRD) calculation, flexibility, and readvanceable features often matter more over time. On a prepayment or refinance, the IRD can cost more than a 0.1% rate gap. Look at the whole package, not just rate.
How does the stress test work — how much can I borrow?
Per OSFI (2026), an uninsured mortgage must qualify at the greater of the contract rate + 2% or 5.25%. How much you can borrow depends on your affordability at that higher ‘qualifying rate,’ not the rate you actually pay. Estimate against it before you shop.
Is a broker channel (First National, MCAP) worth choosing over a big bank?
If you care about rate and prepayment flexibility, it’s worth comparing. These monoline lenders often have lower rates and friendlier IRD, but no branches, broker-only access, and fewer perks. It depends on what you value.
How do the 2024 insured-mortgage reforms affect me?
Per the Department of Finance Canada, since December 15, 2024 the insured price cap rose to $1.5M and 30-year amortizations extended to all first-time buyers and new-build buyers. For first-time buyers that’s a lower barrier and a smaller monthly payment.
