OAS is Canada's universal retirement pension — but there are important choices to make

Almost every Canadian 65+ qualifies for OAS, but when you take it, how long you've lived in Canada, and how much you earn all affect how much you actually keep. This calculator shows the full picture.

💡 OAS Planning Tips for Canadians

⏰ The Deferral Breakeven

Deferring OAS to 70 breaks even at roughly age 82–84. If you expect to live past that, deferral pays off. If you have health concerns, taking it at 65 may be smarter.

💰 Clawback Strategy

If you're near the clawback threshold, TFSA withdrawals don't count as income. Drawing from your TFSA in high-income years protects your OAS from being clawed back.

🌍 Living Abroad

You can receive OAS outside Canada if you lived in Canada for at least 20 years after turning 18. Canada has social security agreements with many countries.

📋 Apply 6 Months Early

Service Canada can only backdate OAS payments 11 months. Apply at least 6 months before you want to start receiving payments to avoid missing any money.
