TL;DR
The best stack is the one that protects your cash-to-close certainty, not the one with the most theoretical tax advantage.
Why this comparison matters
First-time buyers often ask one account question when they actually have a sequence question. The order of contributions can change your usable down payment and first-year stress level.
At-a-glance comparison for 2026 planning
| Option | Core tax profile | Repayment profile | Best use case |
|---|---|---|---|
| FHSA | Contributions generally deductible; qualifying withdrawals tax-free | No repayment for qualifying withdrawals | Base layer for eligible first-time buyers |
| RRSP + HBP | RRSP deduction now, HBP withdrawal tax-free if repaid under rules | Repayment over 15 years | Supplement when FHSA alone is insufficient |
| TFSA | No deduction, growth and withdrawals generally tax-free | No repayment | Flexibility buffer and timing uncertainty hedge |
Recommended stack sequence
- Confirm FHSA eligibility and room, then fill a planned contribution path.
- Add RRSP contributions only when HBP use is realistic and repayment is manageable.
- Keep TFSA liquidity for closing volatility, emergency reserve, and moving-year uncertainty.
One behavior trap to avoid
Anchoring bias
focusing only on the biggest deduction today and ignoring repayment and cash-flow impact during your first ownership year.
