Yes — most lenders accept down payment funds gifted from an immediate family member (parent, sibling, grandparent, or spouse). You’ll need a signed gift letter from the donor confirming the money is a true gift and not a loan that needs to be repaid.
If your mortgage requires default insurance (down payment under 20%), the gifted funds typically need to be in your bank account before your application is submitted for insurer approval. Non-residents and newcomers to Canada sometimes face a higher minimum personal contribution requirement, so this is worth flagging early if it applies to you.
