Switch Cellphone Plans in Canada Without Losing Your Number
Matthew Leo · Published August 12, 2026 · Guides
Switching cellphone providers in Canada is easier than it used to be, but one mistake can still turn a routine port into a headache: cancelling your old line before the new provider moves your number.
If you want to keep your number, leave the old service active and ask the new provider to transfer it. The CRTC says the new provider can handle the transfer and cancellation on your behalf.
Before you switch, check four things: your device balance, your final bill, whether your phone is unlocked, and whether the new plan actually saves money after promotions end.
Do not cancel your old service first
This is the most important step.
The CRTC’s number-porting guidance says your existing service needs to remain active while the new provider starts the transfer. If you cancel first, you can lose the ability to port the number.
Tell the new carrier you want to keep your existing number. It will ask for account details needed to authorize the transfer. Mobile-number transfers often finish within a few hours, although delays are possible.
Keep the old SIM or eSIM active until the transfer is complete.
Check what you still owe on the phone
Leaving a carrier does not erase money still owed on a financed or subsidized device.
Open your account or latest bill and look for the remaining device balance, tab, financing amount or return-option obligation. Some plans separate the wireless service from the phone financing, which can make a cheap monthly rate look easier to leave than it really is.
If you are on a device-return program, check the contract carefully. You may have to return the phone in acceptable condition or make a final payment to keep it.
The key number is not just your monthly plan price. It is the total amount required to leave today.
Activation fees are now prohibited, with limited exceptions
As of June 12, 2026, CRTC rules prohibit fees incurred because a customer activates a new retail telecommunications plan or modifies an existing one.
The rule has exceptions for reasonable physical installation at a customer’s premises and optional products or services the customer explicitly chooses to buy. For a normal cellphone-plan switch, the carrier should not be able to take an ordinary activation charge, rename it and assume the rule no longer applies.
The CRTC has already questioned provider fees that appeared to function like activation charges under different names.
Still, ask the new provider for a written breakdown of every one-time charge before agreeing to the plan.
Your phone should be unlocked
The current Wireless Code requires Canadian providers to supply unlocked phones, and devices that remain locked must be unlocked free of charge.
That matters because an unlocked phone can accept service from another compatible carrier. Before switching, confirm that your device supports the new provider’s network bands and eSIM or physical-SIM setup.
A phone being unlocked does not guarantee perfect compatibility. Devices purchased outside Canada, older phones and some carrier-specific models can lack bands or features used by another network.
Compare the real monthly price, not the launch price
Canadian wireless plans are full of temporary discounts, automatic-payment credits and bundle pricing.
Before switching, write down:
The regular monthly plan price.
How long each discount lasts.
Whether a discount requires automatic payments.
Whether the price depends on having home internet or another service with the same company.
The data amount and whether it includes Canada-U.S. or international roaming.
Any device financing or return-program payment.
A $45 plan that becomes $60 after 12 months is not really a $45 long-term plan. Compare what you expect to pay over at least a year.
Check coverage where you actually spend time
National coverage maps are useful, but they are not the same thing as your daily experience.
A carrier can have excellent national coverage and still perform poorly inside your workplace, apartment, basement or regular highway route. Ask people who use the network in your area, check the provider’s coverage map and make use of any applicable trial period if you are also taking a new device.
The Wireless Code provides a trial period for eligible contracts with an early cancellation fee, allowing a device to be returned in near-new condition within the applicable window if usage stays within the permitted limit. Customers with disabilities receive an extended trial period.
Move two-factor authentication carefully
Your phone number may be tied to banks, email accounts and other services that use SMS verification.
A normal number port should preserve the number, but it is still smart to confirm you can access important accounts before starting. Save recovery codes where available and make sure your email account does not depend entirely on the same phone number for recovery.
During a port, short service interruptions can happen. Do not schedule the transfer five minutes before you need a banking verification code.
Watch for a final bill after the transfer
When the port finishes, the old provider may still issue a final bill for charges up to cancellation, outstanding device amounts or other legitimate balances.
Review it rather than assuming every final charge is wrong. At the same time, challenge any fee that appears to be an activation, modification or prohibited cancellation barrier disguised by a different name.
Keep screenshots or copies of your old agreement, device balance and new offer until everything is settled.
Use this switching checklist
Confirm the new network works where you need it.
Check the remaining device or return-program balance.
Confirm the phone is unlocked and compatible.
Compare the regular price after promotions.
Leave the old service active.
Ask the new provider to port your number.
Keep access to important two-factor authentication accounts.
Review the final bill from the old provider.
The easiest switch is the one you prepare before the sales pitch
Most switching problems happen because customers focus on the new plan and forget the old obligations attached to the phone and number.
Do the boring checks first. Know what you owe, know what the new price becomes later and let the new provider move the number before the old line is cancelled.
Then the switch becomes what it should be: a change of carrier, not a rescue mission for your phone number.
