When the first mortgage is too good to touch.
A second mortgage sits behind the one you already have and leaves it completely alone — same rate, same term, no penalty to break it. It costs more than a first, for a reason worth understanding before you sign one.
A loan behind your loan.
The mechanics below are the Financial Consumer Agency of Canada’s, not our characterisation — source at the foot of the page.
FCAC describes it as a second loan you take on your home, with the same features as a mortgage. Your first mortgage stays exactly where it is — same rate, same term, same lender, untouched.
FCAC states that interest rates on second mortgages are usually higher than on first mortgages, because they are riskier for lenders. If the property were ever sold under pressure, the first mortgage is paid before the second sees anything. That ranking is the whole price difference.
One-time payment, up to 80% of your home's value, repaid in fixed amounts on a fixed term and schedule, covering principal and interest. FCAC's caveat is worth knowing up front: once you pay back what you owe, you cannot borrow it again.
Four situations where a second beats a rebuild.
The clearest case there is. A low rate locked years ago is worth real money, and breaking it mid-term to access equity can cost more in penalty than the second mortgage costs in interest. Leaving it alone is often the cheaper answer even at a higher rate on a smaller amount.
If maturity is years away, waiting is not a plan. A second bridges the gap and can be folded into the first when the renewal window finally opens.
Money needed before the first house sells, without disturbing financing already in place on it. This is one of the more common reasons an officer ends up with a second.
Sometimes the answer is a smaller amount for a shorter time, then a proper restructure at renewal — rather than reorganising everything under pressure at the worst possible moment.
Three shapes, one file.
No rates here on purpose. What decides this is usually the penalty on your existing mortgage against the cost of leaving it alone — a calculation on your numbers, not a table of averages.

Straight answers before you sign.
What is a second mortgage?
The Financial Consumer Agency of Canada describes it as a second loan that you take on your home, with the same features as a mortgage. The important part is what it does not do: your first mortgage is untouched — same rate, same term, same lender — and the second sits behind it. That ranking matters if the property is ever sold under pressure, because the first mortgage is paid out before the second receives anything.
Why is the rate higher than my first mortgage?
Because of that ranking, and FCAC says so directly: interest rates on second mortgages are usually higher than on first mortgages because they are riskier for lenders. A second-position lender is behind the first in line if anything goes wrong, and the price reflects it. What that rate actually is on your file depends on the property, the equity and the lender, which is what we work out rather than quoting a range here.
Should I take a second mortgage or just refinance?
It usually comes down to what breaking your first mortgage would cost. If you locked a good rate years ago and maturity is still far off, the penalty to break it can exceed what a second costs in interest — so leaving it alone wins even at a higher rate on a smaller amount. If your first is due soon, or the rate is no longer competitive, one refinance at first-mortgage pricing is usually cleaner. We price both before recommending either.
Can I get a second mortgage on shift income?
Yes, and the documentation question is the same as any officer file: overtime, shift premiums, court time and paid duty need a consistent history behind them, and how much of that a lender counts varies. Second-mortgage lending also leans more on the property and the equity position than a first does, which sometimes helps a file where the income paperwork is awkward. Send a stub and a mortgage statement and we will tell you where it lands.
What's the difference between a second mortgage and a home equity loan?
They overlap, and FCAC lists them separately. A home equity loan is the lump-sum version: one payment to you of up to 80% of your home's value, repaid in fixed amounts on a fixed term and schedule covering principal and interest — and once you have paid it back, you cannot borrow it again. A second mortgage is the broader category of a loan taken in second position behind your first. In practice the right question is not which label applies but which structure costs you least.
Can I combine it back into one mortgage later?
That is often the plan from the start. A second gets you through the period when breaking the first would be expensive, and at renewal the two can usually be folded together into a single first mortgage at better pricing. Timing that properly is part of setting it up — it is worth knowing the exit before you take the loan, not after.
Price the penalty before you decide.
Send your mortgage statement and a recent pay stub. We will work out what breaking your first would actually cost, what a second would cost instead, and which one leaves you better off. Ramin Hallaji takes these calls personally, around shift work.
