Yes, but the new mortgage usually becomes conventional. A refinance can go up to 80% of your home's appraised value, so you need at least 20% equity to borrow more. You'd pay any prepayment penalty on the old mortgage, so we compare that with the benefit.
The exception is CMHC's secondary-suite refinance, which can go up to 90% if you're adding a legal suite. If you only want a better rate, a straight switch at renewal may cost less. We'll show you which path saves the most.
