How to Renew and Update your Social Insurance Number

In order to accept employment in Canada, you need to have a valid SIN number. You also need it to access government programs and benefits. Often, SIN numbers are given out in a paper format that never expires. That said, there are also plastic cards that are expired. If you have a plastic card, it will need to be renewed before its expiry date.

If you received your SIN number after 2014, you likely don't have a SIN card, just a SIN number. However, just because you don't have a SIN card doesn't mean you no longer have to renew your number. You'll have to renew any time you apply for an SIN, and an expiration date will be given.

What Your SIN Number Says About You

Your Social Insurance Number, also referred to as your SIN Number, is a 9-digit number that identifies you. It's used as a file number and account number for data processing reasons. This number is individual to you; no other person has it. It helps to identify you for tax purposes, pensions and credit history. This number is important, contains sensitive information, and is only meant for certain purposes. This means you have to be careful who you share it with.

In order to gain insurable employment and file your income tax return in Canada, you need to have a SIN number. You can apply for it when you turn 12 years old or when you immigrate to the country. Canadian citizens, permanent residents and temporary residents all need a SIN number.

The main reason that everyone in Canada has a SIN number is to distinguish their identity. The 9-digit number puts you in the social insurance register along with everyone.

Finding Your SIN Number Online

If you're not sure of your SIN number, it's pretty simple to find online. All you need to do is sign into your CRA My Account. If you aren't registered for your CRA My Account or can't get in, you can also find your SIN Number on your:

• Tax slips
• Income tax return
• Record of Employment
• RRSP contribution forms

You can also get a confirmation of your number by submitting an application to the CRA.

Applying For A SIN

There are a few different ways that you can apply for your SIN. One of these ways is to go into Service Canada. You can do this by filling out the online service request form and requesting an appointment. This can be found on the Canada Revenue Agency website. You can leave with your SIN number as long as you have everything you need at the appointment and everything is in order.

You can apply online if you don't want to go into a Service Canada office. It's pretty simple; all you really need to do is submit the required documents and then wait. You can also send them in by mail if you prefer not to online. The documentation required depends on your individual situation and your legal status in Canada. Whether or not you receive approval will depend on if you meet the eligibility criteria.

Getting a SIN with a Study Permit

If you're an international student in Canada in a degree program with a study permit, you can get a SIN number if you meet one of the following conditions:

• Work off-campus or on-campus (as long as you're meeting eligibility criteria)
• When you stop meeting the criteria, stop working

As a temporary resident studying in Canada, as long as you have a SIN, you can work without a work permit as long as you meet the criteria outlined in paragraph R186 of the Immigration and Refugee Protection Regulations.

Just like with foreign workers, this will be a temporary SIN number.

Getting a SIN is difficult if your study permit expires within 30 days. You would then need to get a study permit extension to get your SIN. Once you get an extended study permit, you can apply.

Checking Your SIN Number Status

Once you apply for your SIN number, you are able to check your status. How long it takes for approval depends on how you apply. When you apply in person, you should be able to get your number right away; it's different if you submit a hard copy or online application.

If you apply for your SIN number online, it should only take 5 business days from your application's receipt to be processed. If you provide an email address, you'll receive an email when the application is received, another once it's been processed, and an email if it doesn't meet the requirements. If you haven't received a decision after 10 business days, then you should contact the SIN program directly.

When you apply via mail, as long as everything is correct, it should be processed within 20 business days from the time it was received. If, after 25 business days, you haven't received a letter or an update, that's when you should contact the SIN program directly.ven't received a letter or an update, that's when you should contact the SIN program directly.

How to Renew

You may be wondering why you would have to renew your Social Insurance Number. Not everyone has to, though. The main reason that someone would have to renew their SIN number is if there is a legal change of their name or gender designation. You will also have to renew if your SIN number expires. These are the numbers that start with a 9.

Online

Renewing your SIN online is probably the easiest way to do so. It's a pretty simple process and can be done on the Government of Canada website. You'll need to submit the following documents:

• Proof of address
• A primary identity document that will prove your ID and Canadian citizenship status
• A second identity document
• A copy of an accepted supporting document

Once you've done that, all you have to do is wait for an update.

For Migrants and International Students

As an immigrant, you can apply and renew online, at your local Service Canada Centre, or through the mail. We've already gone over how to renew online, but how would you apply through Service Canada or the mail? The process involves the same conditions and the same steps, but the documentation is slightly different. You must ensure you supply both a primary identity document and a supporting document. A secondary identity document is only required when you renew in person or online.

Valid Documents When Applying and Renewing

When you're filling out your SIN application, you have to provide certain documents. You must provide the correct documents when you're submitting in order to get the fastest decision. Let's take a look at what's accepted.

Temporary Resident SIN Number VS Permanent Resident SIN

While we have discussed that you need a SIN number as a temporary resident as well as a permanent resident, what we haven’t discussed is how these SIN numbers are different. Well, as a temporary resident of Canada, your SIN number is going to start with a 9. This is different from permanent resident numbers and those of Canadian citizens. 

In order to get a temporary resident SIN, you need to provide a valid work permit or a study permit. It’s likely the government will want a copy of the original documents as well as any other relevant immigration documents. It’s important to keep this number as well and renew it when it expires. 

When you get approved for your permanent resident card and get Canadian citizenship, you’ll then have to change your SIN. You do this by reapplying for your SIN number following the same process as before. You may need to provide new immigration documents and proof of your permanent residency. Once it’s verified that you meet the criteria outlined for approval, you’ll receive your new SIN number. 

Do You Have to Renew?

What do you do if you're working or going to school in Canada and your SIN expires soon? Well, don't worry; it's pretty simple to reapply and continue working or studying. This applies to foreign workers and international students who have SIN numbers. Whether you're a temporary worker or a permanent, a number that expires will need to be renewed if you're continuing to work.

Your SIN will expire based on the date provided on your immigration documents. These dates will need to match, so both will have to be renewed. You don't have to worry, though. As long as you apply before the expiry date, you don't have to cease working or going to school while you're waiting for a decision. You must also remain in the country while this process is happening.

While a decision is being made by the IRCC, you'll notice your status will be changed to maintained status (formerly known as implied status). Once the IRCC authorizes the renewal, then you'll receive your new immigration documents. With these new documents, you can apply to change the expiry date on your SIN card so the expiry dates will match. You will not receive a new SIN number; that will stay the same.

You don't always have to worry about renewing your SIN number. If you do, though, the process is relatively straightforward. If there's no expiry date on your SIN number, then that number will stay with you for life.

An Expired SIN Number

When your SIN expires, and you don't renew it, this means you aren't eligible to work in Canada anymore. You would have to reapply to resume your work permit. You're still able to file your income tax return, though, if you haven't already done so. If you have a SIN that will expire and intend to keep working, it's recommended that you apply for an extension before your expiry date.

Do All SINs Expire?

Many Canadians don’t really have to think about their SIN number again once they apply for it. That said, for some, their SIN will expire. If your SIN expires, you will have to renew it before the expiration date. If you do have an expiry date, it will be made very clear once you’re approved. 

In Canada, the expiration SIN numbers are those of temporary workers. These include those working towards their permanent residency but haven’t been approved yet or those who are foreign exchange students. If you’re a Canadian citizen or permanent resident then your SIN number won’t expire. However, the simplest way to know if your SIN expires or not is if it starts with a 9 or not. 

Final Thoughts

In Canada, you need a SIN number to work. Anyone who’s a Canadian citizen, permanent resident, temporary resident and over the age of 12 is eligible for one. If you’re a Canadian citizen or permanent resident, then you will have this number for life. Those who are temporary residents will have to keep renewing this number until they leave the country or become a permanent residents. 

If your SIN number starts with a 9 then it’s considered to be a temporary SIN number. These have to be renewed before their expiration dates. These are common among those with work permits and study permits. All other numbers are permanent and you don’t have to worry about renewals.
