The Home Buyers' Plan lets you withdraw up to $60,000 per person from an RRSP toward a down payment, repaid over 15 years. The First Home Savings Account allows contributions up to $8,000 a year to a $40,000 lifetime limit, deductible going in and tax free coming out.
Eligibility matters more than most buyers expect. These programs generally require that you have not owned and lived in a home in the current calendar year and the preceding four, so a buyer who owned years ago can often still qualify.
