Clients ask this constantly, usually as a complaint about one side or the other. The honest answer is that neither market is overcharging; the two contracts sell different things. Here is what each rate actually buys, so the comparison in your file can be real.
Term length: thirty years versus five
The US thirty-year fixed exists at scale because government-sponsored securitization lets lenders offload decades of rate risk into deep capital markets. Canada's system amortizes over decades but contracts in short terms, so the borrower meets the market again every renewal. Same amortization arithmetic, completely different risk ownership: in the US the lender eats a rate spike after year five; in Canada the homeowner does. A quarter century of payment certainty is not free, and its absence is not a discount, it is a transfer.
Prepayment: option versus penalty
Most conforming US loans can be prepaid or refinanced at any time without penalty, which means every US borrower holds a live option: if rates fall, refinance down; if they rise, keep the old rate and smile. Lenders price that one-way option into the coupon. Canadian fixed terms typically permit limited prepayment and charge for more, with fixed-rate breakage often calculated as an interest rate differential that can run to many months of interest. The Canadian structure is not gratuitous; it protects the funding model that produces the lower sticker. But a borrower who may sell or restructure early is holding a cost the US borrower simply does not have.
Renewal: the meeting Canada cannot skip
Renewal is where the Canadian trade-off collects. Most files renew routinely, but the mechanism has teeth: income changes, credit events or an institution tightening its book can turn a renewal into a new underwriting decision at exactly the wrong moment, a pattern this practice sees weekly. The US structure has no equivalent meeting; the thirty-year contract simply continues. Pricing a cross-border choice without valuing that difference is comparing half the product.
What the gap means inside a cross-border file
For a Canadian buying US property, the sticker gap usually reads as US expensive, Canada cheap. Priced properly it reads differently: the US foreign national or DSCR loan bundles decades of certainty, refinance freedom and currency match with USD rent; Canadian-style leverage offers a lower coupon with renewal exposure, penalty exposure and, if used to fund a USD asset, a currency mismatch on top. Some plans genuinely favour one, some the other, and the deciding inputs are hold period, income currency and exit flexibility, not the two numbers in the ads. That comparison, in your numbers, is a review worth doing before the contract, because after it, the structure owns you.
