If you qualify, an old age pension can be paid to you in Canada but cannot be transferred as a lump sum. For more information or to apply, see https://www.gov.uk/state-pension-if-you-retire-abroad. Before you claim your pension. If you have not already done so, you should investigate making additional lump sum contributions so that you could enjoy a higher pension payment.
You should also be aware that once the state pension starts to pay out, the amount you get is what you are going to get for the rest of your life while in Canada. Unfortunately, residents of Canada (and some other Commonwealth countries) do not enjoy the annual cost of living increase that pensioners in the UK get.
