Yes, you can. As long as you have a valid visa with TRV stamp on the passport and original Permit with expiry more than 3 months away, you do not need any reason to enter in Canada.
P.S. You cannot have VISA without Permit, VISA expiry does not matter if Permit expiry is less than associated VISA, so in your case, check both expiry.
