Canada has long been one of the most popular destinations for Irish emigrants — Toronto, Calgary, Vancouver, and Ottawa have sizeable Irish communities spanning construction workers, nurses, tech workers, and finance professionals. If you spent years paying into the Canadian system and have since returned to Ireland, or if you're planning retirement with contributions in both countries, you have pension entitlements in Canada that are worth claiming. This guide explains how the Canada Pension Plan (CPP), Old Age Security (OAS), and Ireland's PRSI system interact — and what you need to do to collect everything you've earned.
The Canada-Ireland Bilateral Social Security Agreement
Ireland and Canada signed a bilateral Social Security Agreement that came into force in 1992. This agreement does two important things:
- It allows your PRSI contributions in Ireland to be combined (totalised) with your CPP contributions in Canada to help you meet qualifying thresholds in either country.
- It eliminates double contributions — if you're working temporarily in one country while insured in the other, you generally only pay into one system.
Canada Pension Plan (CPP): The Basics
CPP is Canada's earnings-related, contributory state pension — the closest equivalent to Ireland's Social Insurance system. If you worked in any Canadian province except Quebec, you contributed to CPP. Quebec has its own parallel system, the Quebec Pension Plan (QPP), which we cover separately below.
How CPP Contributions Work
In 2026, both employees and employers each contribute 5.95% of earnings between the Basic Exemption (approximately CAD $3,500 per year) and the Year's Maximum Pensionable Earnings (YMPE, approximately CAD $68,500 in 2026). There is also an enhanced second tier called CPP2, which applies to earnings between the YMPE and a higher ceiling — this was introduced in 2024 for higher earners.
Self-employed Canadians pay both the employee and employer shares (11.9% combined), which is worth knowing if you ran your own business there.
What You Can Receive
| Scenario | Monthly CPP (approx. 2026, CAD) |
|---|---|
| Maximum CPP at 65 (39+ years at max contributions) | ~$1,364 |
| Average actual recipient | ~$750–$900 |
| Someone who worked in Canada for 10 years | ~$250–$400 (pro-rata estimate) |
Most Irish returners who spent 5–15 years in Canada will receive a modest but meaningful pro-rata CPP — enough to complement your Irish State Pension rather than replace it. Check your own Statement of Contributions through My Service Canada Account (servicecanada.gc.ca) to see your actual entitlement.
When Can You Take CPP?
The standard CPP start age is 65, but you have flexibility:
- Early at 60: A reduction of 0.6% per month before 65, up to a maximum 36% reduction if you start at exactly 60. This is permanent — it doesn't revert at 65.
- Deferred to 70: An increase of 0.7% per month after 65, up to a maximum 42% uplift at 70. If you have other income and don't need it immediately, deferral usually pays off if you live into your late 70s or beyond.
Old Age Security (OAS): The Residence-Based Pension
OAS is a flat-rate pension funded from Canadian general taxation — not your contributions. It's based on how long you lived in Canada after age 18, not how much you earned or paid in. In 2026, the full OAS is approximately CAD $700/month.
How Much OAS Can You Get?
| Years of Canadian Residency (after 18) | OAS Entitlement |
|---|---|
| Under 10 years | No OAS (unless you return to live in Canada) |
| 10–39 years | Partial OAS (1/40th of full rate per year of residency) |
| 40 years or more | Full OAS (~CAD $700/month) |
If you spent, say, 15 years living in Canada, you'd receive 15/40ths of the full OAS — approximately CAD $262/month — paid to your Irish bank account for life from age 65.
The Critical Difference: OAS Is Not Covered by Totalisation
The OAS Clawback (Recovery Tax)
If your net world income in a tax year exceeds approximately CAD $90,000 (the threshold is adjusted annually), Canada claws back 15 cents of OAS for every dollar above that threshold. At around CAD $148,000, the full OAS is clawed back. For most Irish retirees receiving a combination of Irish State Pension, a modest occupational pension, and OAS, this won't apply — but if you're a high earner with a significant Canadian occupational pension, plan for it.
If You Worked in Quebec: The QPP
Quebec operates its own parallel pension system — the Quebec Pension Plan (QPP) — administered by Retraite Québec (retraitequebec.gouv.qc.ca), not Service Canada. If you worked and paid social contributions while resident in Quebec, your contributions went to QPP, not CPP.
A separate QPP-Ireland agreement applies. The structure is similar to the CPP arrangement, but you must apply directly to Retraite Québec, not the federal Service Canada. If you're unsure which plan you were in, your T4 slips from Canadian employment will show which deductions were taken.
Tax: What Happens When Canada Pays You in Ireland
As an Irish resident receiving CPP or OAS, Canada treats you as a non-resident for tax purposes. The standard non-resident withholding rate on pension income is 25%, but the Ireland-Canada Double Taxation Agreement (DTA), in force since 1967 and subsequently updated, reduces this to 15%.
To get the treaty rate applied from the start — rather than paying 25% and reclaiming the difference — you should file Form NR5 with the Canada Revenue Agency (CRA) before your first payment. If you've already been receiving CPP or OAS at the 25% rate, you can file a Canadian tax return to reclaim excess withholding (within the normal time limits).
In Ireland, Canadian pension income is taxable and must be declared on your annual tax return. You get credit for the Canadian tax withheld under the DTA, so you won't pay double — but the net Irish and Canadian tax rates combined may result in some additional Irish tax if your marginal rate here is higher than 15%.
Practical Steps: How to Claim Your Canadian Pension
- Create a CRA My Account at canada.ca/cra — this lets you see your tax history, T4 slips, and Canadian tax filings.
- Check your CPP Statement of Contributions via My Service Canada Account (servicecanada.gc.ca). This shows every year of Canadian contributions and your projected CPP entitlement at 60, 65, and 70.
- Apply for CPP through My Service Canada Account — you can apply online up to 12 months before you want payments to start. Application is available from age 59 onward (for early start at 60). Provide your Irish bank IBAN for direct deposit.
- File NR5 with CRA before your first payment to get the 15% treaty withholding rate rather than 25%. This requires your Canadian Social Insurance Number (SIN) and Irish address.
- Apply for OAS separately — Service Canada will write to you around your 64th birthday if you have qualifying residency, but you can also apply proactively. OAS and CPP are separate applications.
- Check your Irish PRSI record at MyWelfare.ie to confirm your Irish State Pension entitlement — see our full Irish State Pension guide for thresholds and payment rates.
What About Canadian Occupational Pensions?
Many Irish people who worked in Canada — particularly in the public sector, healthcare, teaching, or large corporations — will also have accumulated benefits in a Canadian Registered Pension Plan (RPP) or a Registered Retirement Savings Plan (RRSP). These are separate from CPP and OAS and are governed by your specific employer scheme or personal savings plan.
RPP benefits are typically paid as a pension from a defined age. RRSP funds must be converted to a Registered Retirement Income Fund (RRIF) or annuity by age 71 under Canadian rules. Both are taxable in Canada at source and in Ireland under the DTA credit system. If you have these, it's worth getting specific cross-border tax advice — the interaction of Canadian and Irish tax treatment of RRSP/RRIF withdrawals is an area where professional guidance pays for itself.

Need personalised advice?
Cross-border pensions are genuinely complex — between the bilateral agreement, withholding taxes, RRSP/RRIF rules, and coordinating two State pensions, there are real decisions to get right. A regulated Irish advisor with international pension experience can map your specific situation, tell you the optimum CPP start age given your other income, and make sure the Canadian tax withheld is properly credited in Ireland.
