If you choose to leave Canada, here are two options on what to do with the money in your GRSP account:
Option 1: You cash out the assets in your GRSP contributions and take the money with you. Remember that any money taken from a GRSP account is taxable income. You will pay an immediate tax on the money you take out, and will permanently lose the contribution room you originally used to make the contribution. More details here.
Option 2: Keep your GRSP contributions at Wealthsimple and withdraw them when retirement time comes!
We highly recommend you talk to your accountant about the best way to move forward.
