Home Buyers’ Plan: Registered Retirement Savings for down payments. Canada Revenue Agency’s Home Buyers’ Plan lets qualifying home buyers use up to $25,000 of their Registered Retirement Savings Plan (RRSP) to buy a home. Couples can use up to $50,000. The home must be the principal residence, the home buyers must not have owned a home within the past five years and the loan must be repaid within 15 years.
