Both The Toronto Star’s Ellen Roseman (thanks for the mention!) and Financial Post’s Jonathan Chevreau have pointed out that the Canadian Tire’s One-and-Only account has an advantage that I had overlooked: the mortgage can in paid in full at anytime, whereas a conventional mortgage has limited prepayment privileges.

Personally, we have a fixed-rate, 5-year mortgage that allows us to increase our monthly payment by 25% and make a total annual prepayment of 20% of the original loan value without any penalty. A lump sum prepayment of any amount (as long as the total annual prepayments stay within the 20% limit) can be made at the same time as the regular mortgage payment. Even though we pay down our mortgage aggressively, I find it difficult to make the maximum prepayment every year. I wonder if the open nature of the One-and-Only account, albeit at a higher rate, will appeal to many mainstream customers.
