How do I make a complaint about a bank in Canada?
Complain to your bank first and note the date. It must give you a detailed written response within 56 calendar days. If it doesn’t, or you disagree with its final response, you can take the complaint to OBSI free of charge within 180 calendar days. OBSI can recommend up to $350,000, but its recommendations aren’t binding.
The process at a glance
- Gather the facts
Statements, dates, who you spoke to, and what outcome you want (a refund, a correction, an apology). - Complain to the bank
Use its published complaint procedure — online, by phone, in branch or in writing. Note the date: it starts the clock. - Wait up to 56 days
The bank must give you a detailed written response within 56 calendar days of your first complaint. FCAC expects that clock to run without pauses. - Escalate to OBSI
You can go to OBSI when 56 days have passed, or earlier if the bank gives its final written response and closes the file. OBSI is free. - Tell FCAC about rule-breaking
FCAC doesn’t resolve individual complaints, but it wants to hear if you think a bank broke a consumer-protection obligation.
Deadlines to watch
| Step | Time limit |
|---|---|
| Bank’s detailed written response | 56 calendar days from your first complaint |
| Bringing the complaint to OBSI | OBSI says within 180 calendar days of the firm’s final response |
| OBSI telling you it can’t take the case | Within 30 calendar days |
| OBSI’s final written recommendation | Within 120 calendar days after it has the information it needs |
| Reporting an incorrect pre-authorized debit to your institution | Usually 90 calendar days from the withdrawal |
Why OBSI, and only OBSI
Until 2024 banks could choose between two external complaint bodies. Since November 1, 2024, OBSI is the single external complaints body for federally regulated banks, overseen by FCAC. ADR Chambers Banking Ombuds Office is no longer an option for bank complaints.
What can OBSI actually do for me?
OBSI investigates and makes recommendations. It can recommend compensation of up to $350,000 for a single complaint, and the limit does not rise when more than one account is involved. Its recommendations are not binding: a bank doesn’t have to follow them. If a bank refuses, OBSI makes public that the bank did not comply, without naming you.
How often does going to OBSI pay off?
In fiscal 2025 (November 1, 2024 to October 31, 2025), its first full year as the single banking ombudsman, OBSI opened 5,438 banking cases. About 25% of closed banking cases ended with money paid to the consumer. Most cases don’t end with compensation, so go in with realistic expectations and good evidence.
Worked example: counting the days
Say you first complain to your bank on March 3. Count 56 calendar days: 28 days take you to March 31, and 28 more take you to April 28. If you have no final answer by then, you can go to OBSI.
Now say the bank sends its final written response on April 10 instead. You can go to OBSI right away, and you have 180 calendar days from that response to do it — until about October 7.
Both clocks count calendar days, so weekends and holidays count too. Mark both dates in your calendar the day you complain.
What must the bank give me when I complain?
- A written acknowledgment of the date it received your complaint.
- Information about its complaint procedures and how to use them.
- A detailed written response within 56 days of your first complaint.
The Bank Act also says a bank must not describe its complaint process or staff in misleading terms, and gives “ombudsman” as an example of a word that suggests independence. However it is named, a bank’s internal complaints office is part of the bank. OBSI is the independent step.
Should I go to court instead?
You can, but speak to a lawyer early. OBSI says participating firms must sign a tolling agreement with you, to the extent the law allows. It pauses the legal limitation clock from when OBSI receives your signed consent letter until 30 days after its final letter, or when the investigation ends. If you have already started a lawsuit, you must agree not to proceed until OBSI finishes. Using OBSI doesn’t take away your right to sue afterwards.
There is also an outer limit: OBSI won’t take a complaint you didn’t raise with your bank within six years of when you knew, or should have known, about the problem.
Who do I contact for what?
| Your situation | Where to go |
|---|---|
| A fee, error or service problem with your bank | The bank’s complaint process, first |
| No answer after 56 days, or you disagree with the final response | OBSI, within 180 days of the final response |
| You think the bank broke a consumer-protection rule or public commitment | FCAC — it supervises compliance but won’t resolve your case |
| A problem with a provincial credit union | The credit union first, then OBSI or your provincial regulator |
Common mistakes
- Not recording the date of your first complaint. Both the 56-day clock and your OBSI timing depend on it.
- Waiting more than 180 days after the bank’s final response.
- Treating the bank’s internal complaints office as independent.
- Sending opinions instead of evidence. Statements, letters and screenshots carry weight.
- Expecting FCAC to get your money back. FCAC does not resolve individual complaints.
What to ask the bank
- What is my complaint reference number, and what date do you have as received?
- Who is handling it, and how do I reach them?
- When will I get your detailed written response?
- Is this your final response? If not, when will it come?
Credit union members
Federal credit unions follow the bank process (56 days, then OBSI). For provincially regulated credit unions, OBSI says credit unions in British Columbia, Alberta, Saskatchewan, Manitoba, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador offer its services to members, with a 90-day firm-response period. Ontario and Quebec members should check their credit union’s process and provincial regulator. See your province in the credit union directory.
Writing a complaint that gets read
- One page: what happened, when, the account involved, and the outcome you want.
- Attach evidence, not opinions — statements, screenshots, letters.
- Ask for the response in writing and keep copies of everything.
- Stay polite and specific; it helps if the file later reaches OBSI.

Write down the date of your first complaint. Both the 56-day clock and your right to go to OBSI depend on it.
What this means for you
A complaint is mostly a matter of dates and evidence. Get those right and you keep every option open.
- On day one: note the date you first complain, and ask for a reference number and the date the bank has recorded. The bank must acknowledge that date in writing.
- In your calendar: add 56 calendar days. If you have no detailed written response by then, you can go to OBSI. Weekends and holidays count.
- When the final response arrives: if you disagree, you have 180 calendar days from it to take the complaint to OBSI. Don’t let it drift.
- If the problem is old: OBSI won’t review a complaint you didn’t raise with the bank within six years of when you knew, or should have known, about it.
- If the bank broke a rule: report it to FCAC as well, but don’t expect FCAC to recover your money.
Set realistic expectations. OBSI is free and can recommend up to $350,000, but its recommendations aren’t binding, and about a quarter of closed banking cases ended with money paid to the consumer. A short, specific complaint backed by statements, letters and screenshots gives you the best footing. A bank’s internal complaints office is part of the bank, whatever it is called; OBSI is the independent step.
If you are weighing court, speak to a lawyer early about your own limitation deadline. If you bank at a provincial credit union, check its route in the credit union directory — where OBSI is offered, the firm-response period is 90 days, not 56.
