The Home Buyer's Plan allows you to remove up to $20,000.00 from your RRSP in order to purchase a first home. A first home means that neither of you can have been a home owner for the previous four years.
Married and common law couples may each contribute up to $20,000 from RRSP's towards a purchase ($40,000 in total).
