No, you can use both your First Home Savings Account (FHSA) as well as make a withdrawal from your Registered Retirement Savings Plan (RRSP) under the Home Buyers’ Plan (HBP) to purchase a qualifying home. Keep in mind that with a HBP withdrawal, you’ll have to repay any funds you withdraw from your RRSP. There is no repayment requirement for withdrawals from an FHSA.
