Your Carrier Overcharged You. Here Is Exactly How to Get Your Money Back.

You checked your bill and something is wrong. A roaming charge you did not authorise. A price increase you were never told about. A fee for a service you never used. Or a plan price that does not match what you were quoted when you signed up.

You are not powerless. Canadian carriers operate under a regulatory framework that gives consumers specific, enforceable rights -- and there is a free, independent process to hold carriers accountable when they violate those rights. Most Canadians have never heard of it.

Here is the exact path from unexpected charge to resolution.

Step 1 -- Identify Exactly What Was Charged and Why

Before calling anyone, do this first. Pull up your current bill and your previous three bills and compare them line by line. Carriers bury changes in line items that are easy to miss -- administrative fees, network access fees, regulatory recovery fees, and device financing charges all appear as separate lines.

Write down the specific charge or line item that is wrong, the amount and the date it first appeared, what you believe you should have been charged instead, and any written confirmation of the original price -- a welcome email, an online order confirmation, or a screenshot of the plan page when you signed up.

Having this documented before you call gives you a clear, specific complaint rather than a vague dispute. Carrier agents are trained to handle vague complaints with partial credits and apologies. Specific, documented complaints are harder to dismiss.

Step 2 -- Call Your Carrier and Ask for a Credit

Call the customer service number on your bill and state your complaint clearly and specifically. Do not say you are unhappy -- say exactly what was charged, why it is wrong, and what resolution you expect.

Example: "My bill increased by $5 in June with no notification. I am on a month-to-month BYOD plan and I did not agree to a price increase. I am requesting a credit for the overcharge and confirmation of my correct monthly rate."

During the call: get the agent's name and note the date and time, ask for a reference number for the complaint, and if the agent offers a partial credit ask why it is not a full credit. If the agent says the charge is correct and refuses to reverse it, do not argue -- escalate.

Step 3 -- Escalate to a Supervisor

If the first agent cannot or will not resolve the issue, ask to speak to a supervisor or a retention specialist. Do not accept "that is our policy" as a final answer.

When speaking to a supervisor, reference the CRTC's Wireless Code. Carriers are legally required to comply with the Code, which covers billing accuracy, contract terms, and notification requirements for price changes. Mentioning that you are aware of the Wireless Code and your rights under it signals that you know the escalation path and changes the tone of the conversation.

The most relevant Wireless Code protections: carriers must provide 30 days written notice before making changes that result in increased charges; they cannot charge for services not agreed to in your contract; roaming charges cannot exceed $100 per line per billing cycle without explicit consent; and they must provide itemised bills that clearly identify all charges.

If the supervisor resolves the issue, get the resolution confirmed in writing -- either ask them to send a follow-up email or request a reference number and note exactly what was agreed.

Step 4 -- File a Complaint with the CCTS

If your carrier refuses to resolve the issue after escalation, the Commissioner for Complaints for Telecom-television Services is your next step. The CCTS is an independent, government-backed organisation that mediates disputes between Canadian consumers and their carriers. Filing a complaint is free and the process is entirely online.

The CCTS accepts complaints about being overcharged due to a billing error, being charged a price different from what was advertised or agreed to, being billed for services you did not use including unauthorised roaming charges, problems during number porting or service transfers, service quality issues and unreasonable interruptions, and contract terms not being honoured.

The CCTS cannot help with complaints about the general price level of plans -- if you think Canadian wireless is too expensive broadly, that is a policy issue, not a CCTS complaint. But if a carrier charged you something specific that was wrong, the CCTS is exactly the right place.

How to file:

Go to ccts-cprst.ca
Click "File a Complaint"
Fill in your carrier, the nature of the complaint, the amount in dispute, and the steps you have already taken to resolve it with your carrier
Upload any supporting documentation -- bills, screenshots, emails

The CCTS will contact your carrier on your behalf. Carriers take CCTS complaints seriously -- the process has real consequences and carriers are required to respond. Most complaints are resolved within 30 days. There is no cost to you regardless of the outcome.

The Most Common Overcharges in Canada

Unexpected price increases. Carriers can raise prices on month-to-month plans with 30 days notice, but they must provide that notice. If your price went up and you did not receive written notification 30 days in advance, that is a Wireless Code violation and grounds for a credit.

Roaming charges on domestic flights. Several Canadian flight routes pass over US airspace, triggering $16/day roaming charges on a domestic trip. These are among the most commonly disputed charges and among the easiest to get reversed -- you were on a domestic flight and had no intention to roam.

Administrative fee increases. Carriers add and increase administrative fees regularly. These are separate from your plan price and can be raised with less scrutiny than plan rates. Check whether a new or increased administrative fee appeared on your bill without notice.

Charges after cancellation. Customers who cancel their service sometimes receive bills for the period after their stated cancellation date. Document your cancellation date and request in writing -- confirmation emails are your evidence.

Pay-per-use charges. Data, international texts, or calls billed at pay-per-use rates when your plan should have covered them. Often happens during plan migrations when features are not correctly transferred.

What to Do If Your Price Just Went Up

If you received a notice that your plan price is increasing, you have options beyond just paying the new rate. Under the Wireless Code, a price increase on a fixed-term contract entitles you to cancel without penalty within 30 days of receiving the notice. For month-to-month plans, you can switch carriers at any time -- and after June 12, 2026, there are no activation or cancellation fees on plan switching.

A price increase notification is often the best time to compare what is available on the market. The carrier is changing the terms -- you are not obligated to accept them.
