Yes, you can transfer money from your RRSP to your FHSA. The transaction won't trigger any tax consequences as long as it's a direct transfer and doesn't exceed your annual FHSA contribution room. However, you cannot claim this transfer as a deduction on your tax return. Furthermore, that contribution room won't be available for your RRSP the following year. Should you decide not to use the funds in your FHSA to purchase a home, you can later transfer the funds back to your RRSP tax-free.
