A simple comparison
Each program starts from a different connection.
Connected mainly to contributions
CPP is a retirement pension based primarily on your CPP contribution record from work.
- Main connection
- Valid work contributions and any contribution credits that apply.
- How it can fit
- CPP can be received alongside OAS. Workplace pensions and savings are separate income sources.
- Details to confirm
- Your contribution statement and estimate, including any credits, QPP history or international work.
Connected mainly to residence
OAS is based on age, legal status and years of Canadian residence rather than on how much you worked.
- Main connection
- Age, legal status and years of Canadian residence—not work contributions.
- How it can fit
- OAS can be received with CPP. GIS is available only to eligible lower-income OAS recipients.
- Details to confirm
- Your residence record, the rules for living inside or outside Canada and any recovery tax.
Connected to OAS and income
GIS is additional support for eligible lower-income people who receive OAS.
- Main connection
- Receiving OAS, living in Canada and meeting the current income and other eligibility rules.
- How it can fit
- GIS is added to the OAS payment when someone qualifies. Not every OAS recipient receives GIS.
- Details to confirm
- Current income thresholds, household category, sponsorship rules, tax filing and application status. Read the GIS guide.
CPP and OAS may both appear in one retirement-income picture. GIS may be an additional line when its current rules are met. Employment income, workplace pensions and withdrawals from savings remain separate. Not everyone receives every source.
Timing and related questions
CPP and OAS timing is a separate question.
CPP and OAS do not have to start together, and receiving CPP is not required to receive OAS. The timing guides explain the broad factors without selecting a start date.
QPP, international work and residence outside Canada can add different rules. Confirm those circumstances through the current official guidance.
