When you're wrapping up your time in Canada—after studies, a working holiday, or an overseas posting—it's easy to get swept up in packing and moving logistics and leave your phone, banking, and tax admin until the very end. But the most common “uh-oh” moment after leaving Canada usually isn't something in a box. It's a digital login. The bottom line: the single most important thing to do before you go is to make sure you can still log in to your Canadian services after you leave. If you check your phone number, SMS verification, account details, and CRA (Canada Revenue Agency) sign-in while your Canadian number still works, everything afterward gets a lot smoother. This article lays it all out as a simple checklist.
- Top priority: stay able to log in after you leave Canada
- Set up non-SMS verification while your number still works
- Check CRA, banking, and credit card sign-in before you cancel
- Keeping a number and getting data are easier when you treat them separately
- Start about 3–4 weeks before you leave for peace of mind
- The first thing to do is make sure you can still log in after you leave Canada. Confirm your number, SMS verification, account details, and CRA sign-in while you're still in Canada.
- If you want to keep your Canadian number, an inexpensive annual keep-your-number plan can hold it cheaply. If you plan to cancel, set up non-SMS verification first, then decide.
- For data while you're still in Canada or on a future trip back, you can add an eSIM separately—independent of keeping your number.
The information here is general and current as of June 2026. Terms for banks, the CRA, credit cards, and money-transfer services can change, and we don't make definitive claims about any individual case here. Always check the latest details on each provider's official site before you act.
First and most important: stay able to log in after you leave
Almost every post-departure headache comes down to “I can't log in” or “I can't receive the verification code.” Many services text a confirmation code to the phone number on file when you sign in. If you cancel your Canadian number—or you simply can't receive that number's SMS once you've left—you can get stuck at this step.
That's where SMS verification backup comes in. The idea is to set up alternative verification that doesn't rely on a phone number or SMS—email verification, an authenticator app, or backup codes—so you can still sign in after you leave. The key is to do this while your Canadian number is still active, so you avoid the trap of “I can't even re-set-up my authenticator app without that number.” Continuing to receive Canadian SMS after you leave is another option; we cover how that works and what to watch out for in our guide to receiving Canadian SMS verification after you leave.
When should you start? (Aim for 3–4 weeks out)
Our recommendation is to start your digital prep about 3–4 weeks before you leave and chip away at it. Setting up an authenticator app or saving backup codes can be done in a single sitting, but checking whether a bank supports non-residents—or getting documents sent to you—can take time between asking and getting an answer. This order tends to flow well:
- 3–4 weeks before: Check your account details (number, email, address) for the CRA, your bank, credit cards, and transfer services, and enable non-SMS verification.
- 2 weeks before: Decide whether to keep or cancel your Canadian number. If you're keeping it, arrange a keep-your-number plan.
- 1 week before to the last day: Decide whether to keep or convert your Canadian dollars, and update your contact details (email) so you can still receive any documents you need.
Before-you-leave checklist (phone, banking, CRA, credit cards)
Work through the table from top to bottom and you won't miss anything. Your phone, your money, and your verification are all connected, so it's reassuring to check them together.
| Category | What to do |
|---|---|
| Phone | Decide whether to keep your Canadian number / choose a keep-your-number plan / check whether you can receive SMS and use Wi-Fi Calling from abroad / confirm your device supports eSIM |
| Banking | Confirm your registered phone number, email, and address / account maintenance fees / transfer methods / whether non-residents can keep using the account |
| CRA (taxes) | Confirm sign-in / set up backup multi-factor authentication (passcode grid, authenticator app) / change your address |
| Credit cards & transfer services | Identity verification method / update your registered number / enable app-based verification |
| Insurance, school, former employer | Update your contact email / how you'll receive any documents you need |
| Canadian dollars | Keep them or convert to your home currency / non-resident handling for interest-bearing accounts and GICs |
Services to check before you cancel your number
If you cancel your Canadian number and only then realize “this service required that number to verify me,” getting back in can be a hassle. Before you cancel, run through the main services tied to your number all at once. The same logic applies to cancelling any phone number—there's a lot of overlap with what to check before cancelling a phone number, so it's a useful reference if you're unsure.
| Service | What to check |
|---|---|
| Canadian bank | Registered number, verification method, non-resident support |
| CRA | Sign-in, backup verification, address |
| Transfer services | App-based verification, how to update your number |
| Credit cards | Identity verification, registered number |
| Brokerage & investments | Verification method, non-resident account terms |
How accounts and investment products are handled once you're a non-resident depends on each provider's rules and your individual situation. We don't make definitive claims here—check the latest terms in each bank's or brokerage's official guidance.
Who should keep their Canadian number, and who can cancel
It's easiest to decide based on three questions: will you keep using Canadian services after you leave, is SMS verification something you can't drop, and do you plan to return to Canada.
| Better to keep | Okay to cancel | |
|---|---|---|
| Finance & CRA | Will keep using after leaving | Will rarely use |
| Verification | Can't drop SMS | Already switched to non-SMS |
| Returning to Canada | Plan to | No plans to |
Who this prep is for, and who it isn't
Good fit
- Anyone leaving Canada after studies, a working holiday, or an overseas posting
- Anyone who wants to sort out where to start with their departure prep
- Anyone who'll keep using a Canadian bank, the CRA, or Canadian credit cards after leaving
Not a fit
- Anyone who won't really use Canadian services going forward
- Anyone who has already sorted out their verification and account details
Treat data separately from keeping your number
It's easy to overlook, but keeping your Canadian number does not mean you have to hold on to an expensive data plan too. You can keep the number on a cheap annual keep-your-number plan and add just the data you need—while you're still in Canada, or on a future trip back—separately. That keeps your fixed monthly cost down while letting you boost your data only when you actually need it. One option for adding data on its own is a data-only eSIM. You can pick a capacity for anything from a short trip to a longer stay, and search by destination, capacity, and number of days on Bloomy's comparison page. Pricing and coverage areas change, so confirm the latest details as shown on the comparison page.
[bloomy_price_table]Bloomy is a data-only eSIM. It does not include a phone number for calls or texts—so voice calls and SMS over a phone number aren't available—but app-based calls that run over data, like WhatsApp, Messenger, and FaceTime, work as usual. If you specifically need a Canadian number or SMS verification itself, consider it alongside a separate option such as a keep-your-number plan. A fair-use policy applies, and actual speeds and quality depend on the local network, your device, and the area, and prices may vary—please confirm at the time of purchase.
So you're not caught out after leaving or on a return trip (common slip-ups)
These are easy stumbles you can avoid with a little prep.
- Cancelling your number, then getting stuck on CRA or bank verification: set up non-SMS backup verification while your number still works.
- Forgetting to set up CRA backup verification: set up your passcode grid or authenticator app while you're still in Canada.
- Not checking non-resident account terms: confirm with each bank or brokerage in advance whether you can keep using the account after you leave.
- Getting tripped up by your home-country number's verification on a return trip: if you plan to head back to Canada or abroad again, it's worth also preparing for receiving your home country's SMS verification while abroad.
What to do next
- Check the verification methods and account details for your Canadian bank, the CRA, transfer services, and credit cards
- Set up CRA backup verification and app-based verification for your transfer services
- Decide whether to keep your Canadian number, and choose a keep-your-number plan if you do
- Decide whether to keep or convert your Canadian dollars, alongside non-resident support
- Plan to add data with an eSIM for time in Canada or a return trip
Wrap-up
The key to prepping for life after Canada is making sure you can still log in once you've left. If you get your number, SMS verification, account details, and CRA sign-in sorted while your Canadian number still works, you're far less likely to run into trouble later. Keep your number cheaply on an annual keep-your-number plan if you need it, and add data separately with an eSIM to travel light. No need to rush—just work through this checklist one item at a time.
