How to Apply for Old Age Security (OAS)
Applying for Old Age Security (OAS) is an important step in preparing for retirement. While many Canadians are automatically enrolled and begin receiving benefits without submitting an application, others must apply through Service Canada to start their monthly pension.
Understanding when to apply, what documents you may need and how the application process works can help ensure your payments begin as expected and avoid unnecessary delays.
Do You Need to Apply for OAS?
Not everyone needs to submit an application. Service Canada automatically enrolls many eligible Canadians and usually sends a notification letter before they reach age 65.
If you do not receive an enrolment notice, you may need to submit an application yourself. Checking your status before your 65th birthday is recommended.
| Situation | Application Required? |
|---|---|
| Automatically enrolled | No |
| No enrolment letter received | Usually yes |
| Unsure of your enrolment status | Check My Service Canada Account or contact Service Canada. |
When Should You Apply?
If you are not automatically enrolled, it is generally recommended to apply several months before you would like your Old Age Security pension to begin. Applying early gives Service Canada time to review your eligibility and process your application.
If you plan to delay your OAS pension beyond age 65 to receive a higher monthly payment, you can indicate your preferred starting date during the application process.
Ways to Apply for Old Age Security
Eligible Canadians can generally apply for Old Age Security online through My Service Canada Account or by submitting a paper application to Service Canada.
| Application Method | Available? |
|---|---|
| My Service Canada Account (online) | Yes |
| Paper application by mail | Yes |
| Service Canada assistance | Available if you need help completing your application. |
Information You May Need
Before beginning your application, gather the information and documents that may be required to verify your identity and residency history.
| Information | Purpose |
|---|---|
| Social Insurance Number (SIN) | Identifies your government records. |
| Personal identification | Confirms your identity. |
| Banking information | Sets up direct deposit for your payments. |
| Canadian residency history | Determines OAS eligibility and payment amount. |
| Immigration documents (if applicable) | May help establish residency status. |
What Happens After You Apply?
Once Service Canada receives your application, it reviews your eligibility based on the Old Age Security Act. If additional information is required, you may be contacted before a final decision is made.
After your application is approved, you will receive information explaining when your monthly payments will begin and how much you are expected to receive.
How to Apply Online Through My Service Canada Account
For many Canadians, the fastest and most convenient way to apply for Old Age Security is through My Service Canada Account (MSCA). The online application allows you to submit your information securely and monitor the progress of your request.
Before starting, make sure your personal information, residency history and banking details are accurate to help avoid unnecessary delays.
| Step | Action |
|---|---|
| 1 | Sign in to My Service Canada Account. |
| 2 | Select the Old Age Security application. |
| 3 | Complete the required personal and residency information. |
| 4 | Provide your direct deposit details if applicable. |
| 5 | Review and submit your application. |
How to Apply by Mail
If you prefer not to apply online, you may be able to complete a paper application and mail it to Service Canada. This option is available for eligible applicants who prefer traditional paper forms or cannot access the online service.
Be sure to complete all required sections and include any supporting documents requested. Missing information can delay the processing of your application.
| Paper Application Checklist | Status |
|---|---|
| Application completed | Required |
| Supporting documents attached (if requested) | Required |
| Application signed | Required |
| Mailed to the appropriate Service Canada office | Required |
How Long Does an OAS Application Take?
Processing times vary depending on your individual circumstances and whether Service Canada requires additional information to verify your eligibility or residency history.
Submitting a complete application with accurate information and supporting documents can help reduce processing delays.
| Application Situation | Possible Processing Impact |
|---|---|
| Complete application | May be processed more efficiently. |
| Missing documents | Additional review may be required. |
| Complex residency history | Verification may take longer. |
| International residency | Additional documentation may be requested. |
Can You Delay OAS When Applying?
Yes. If you prefer not to begin receiving Old Age Security at age 65, you can generally choose to delay your pension during the application process.
Delaying OAS results in a permanently higher monthly payment once your pension begins. Many Canadians choose this option if they continue working or have sufficient retirement income from other sources.
| Starting Your Pension | General Effect |
|---|---|
| Age 65 | Standard monthly OAS payment. |
| After age 65 | Higher monthly pension. |
| Up to age 70 | Maximum delayed pension increase may apply. |
Common Application Mistakes to Avoid
Many application delays can be avoided by reviewing your information carefully before submitting your request. Taking a few extra minutes to verify your details can help ensure your application is processed as smoothly as possible.
| Common Mistake | How to Avoid It |
|---|---|
| Incorrect personal information | Review all information before submitting. |
| Missing residency details | Provide a complete Canadian residency history. |
| No banking information | Set up direct deposit when possible. |
| Applying too late | Submit your application several months before your desired start date. |
| Missing supporting documents | Attach all requested documents before submitting. |
How to Check the Status of Your OAS Application
After submitting your Old Age Security application, you can monitor its progress through My Service Canada Account (MSCA). The online portal allows eligible applicants to review updates, verify submitted information and determine whether additional documents are required.
Checking your application status periodically can help you respond quickly if Service Canada requests further information during the review process.
| Service | Available Through MSCA |
|---|---|
| View application status | Yes |
| Review submitted information | Yes |
| Update contact details | Yes |
| Manage direct deposit information | Yes |
What Happens If Your Application Is Delayed?
Some applications require additional review before Service Canada can make a decision. Delays may occur if supporting documents are missing, residency history needs verification or additional information is required.
If Service Canada contacts you for more information, responding promptly can help reduce further processing delays.
Can You Update Your Application After Submitting It?
Yes. If your contact information, banking details or personal circumstances change after submitting your application, you should notify Service Canada as soon as possible.
Keeping your information up to date helps ensure that future correspondence and benefit payments are not delayed.
| Information That Can Change | Why It Matters |
|---|---|
| Mailing address | Ensures you receive important correspondence. |
| Banking information | Allows direct deposit payments to continue without interruption. |
| Phone number or email | Makes it easier for Service Canada to contact you if needed. |
| Residency information | May affect eligibility or payment calculations. |
Applying for OAS While Living Outside Canada
Canadians living abroad may still be eligible to apply for Old Age Security if they satisfy the applicable residency requirements or qualify under an international social security agreement.
Applications involving periods of residence outside Canada may require additional documentation, so processing times can sometimes be longer than for applicants living in Canada.
| Situation | Possible Requirement |
|---|---|
| Living outside Canada | Additional residency verification may be required. |
| International social security agreement | Supporting documentation may be requested. |
| Recent move abroad | Service Canada may review residency history. |
Preparing for Your First OAS Payment
Once your application has been approved, you should confirm your direct deposit information, review your payment schedule and understand how your OAS pension fits into your overall retirement income plan.
Many retirees receive OAS alongside CPP benefits, workplace pensions, RRIF withdrawals or the Guaranteed Income Supplement, depending on their circumstances.
- Confirm your banking information.
- Save the annual OAS payment calendar.
- Review your approval letter carefully.
- Understand your expected monthly payment.
- Keep your personal information up to date.
