I guess this is one of the last round of large banks who has officially decreased its tax free savings account interest rate. BMO originally had a 3.0% interest rate and as you can see here today that has apparently dropped to 2.25%
So by the looks of it people were only able to enjoy a one month rate of the initial 3%. Although, one good thing is this bank apparently had no transfer fee. So if you were thinking of switching then you can do it without too much worry.
