My fixed mortgage at 2.69% is up April 2020 where lump sum payments dont affect current interest payments. I have 15k sitting in my chequings account and 8k in a cheesy lowest interest ever TFSA. I have seen GIC ads for 3% interest for a one year term and am curious if I would be better off putting 20k(the amount I am comfortable not having access to) into that for one year and then when remortgaging comes around I will have access to my small amount of interest earned on top of the 20k to dump into mortgage before i remortgage at what i presume will be a much higher rate,or if i should just put it on the mortgage now and be done with it?I am new to this forum,new to investing and the whole financial world,just happen to have a lot of money kickin around and am ready to start being more responsible.Thanks for your time and sorry for my ignorance.
