About TD Canada Trust
TD Canada Trust is the retail bank of TD, one of Canada's Big Five banks.
TD prepayment privileges
On a closed TD mortgage you can prepay up to 15% of the original amount borrowed each year, and increase your regular payment — the increases together can reach 100% of your original principal-and-interest payment. Model what a lump sum does to your amortization in the prepayment savings calculator.
Porting a TD mortgage
TD lets you port the mortgage to a new home: the principal, rate, remaining term and amortization move with you, with no prepayment charge on the ported amount.
How TD calculates the penalty to break
Variable closed mortgages are typically charged three months' interest. Fixed closed mortgages pay the greater of three months' interest or an interest rate differential (IRD) that uses TD's posted rate for a similar mortgage, minus the discount you received. Estimate the difference between the two methods in the mortgage penalty calculator.
What that means for you
TD's payment-increase room is unusually generous, which makes it easy to shorten the amortization without touching the lump-sum allowance. Because the IRD is based on posted rates less your discount, the break penalty on a fixed mortgage can be large — worth pricing before you sign if a move or refinance is possible.
How this calculator works
Canadian fixed-rate mortgages state their rate compounded semi-annually, not in advance — the convention that follows from section 6 of the federal Interest Act. The calculator converts the rate you enter into the equivalent rate for your payment frequency, so monthly, bi-weekly and weekly results stay consistent. Accelerated bi-weekly pays half the monthly amount every two weeks, which adds the equivalent of one extra monthly payment a year.
