A bank complaint can become difficult to follow when every conversation produces a new reference and nobody explains whether the original issue has been decided. The practical answer is to keep one chronology, identify the decision you are challenging and preserve the date on which you first complained. That record also supports an external review.
This guide concerns personal banking complaints involving Canadian banks and federal credit unions. It explains the bank's complaint process and escalation to the Ombudsman for Banking Services and Investments, or OBSI. Provincial credit unions and investment firms can have different timelines. Official guidance was checked on 21 October 2026; this is not a promise that an individual claim will succeed.
1. Identify the institution and the disputed service
Use the legal name on the account agreement or statement. A familiar brand can cover several businesses, and a banking complaint is not automatically the same as a complaint about a separately supplied investment or insurance product. Record the account type, relevant transaction and institution that made the disputed decision.
OBSI's participating firm search helps identify a firm within its service. Check the name rather than relying on a logo alone. If the institution's status is unclear, ask which complaint process and external body apply to the particular product before using a timeline meant for another sector.
Frame the issue specifically. “The bank is unfair” does not explain whether you dispute a charge, an unauthorized payment investigation, an account record or information provided before a transaction. Write one sentence describing the problem, followed by the correction or payment sought. Separate unrelated issues so each can receive a clear answer.
2. Preserve the first complaint date
The Financial Consumer Agency of Canada's current complaint guide says a bank must provide a detailed written response within fifty-six calendar days from the first complaint. Keep the first message, call record or branch contact and any acknowledgement. A later referral to a specialist should remain connected to that original chronology.
If the initial contact was by telephone, make a dated note of what you said, whom you spoke to and the reference given. Follow with a short written confirmation through a secure channel. Distinguish the date of a routine information request from the date you communicated dissatisfaction and asked the bank to address it.
Ask the bank to confirm the complaint's recorded opening date. If its date differs from yours, attach the earlier evidence and request an explanation. Do not silently replace the first date with the latest case number. Equally, do not claim you complained before the problem was actually raised.
3. Use the internal process without losing the thread
Obtain the bank's published complaint-handling steps. FCAC's statement of complaint rights explains the information and handling protections banks must provide. Use the designated route and ask how to move an unresolved issue to the next internal level.
Send the same core file when the matter moves teams: a short summary, chronology, evidence index and requested remedy. Add the latest reply rather than rewriting the whole history. If an employee says a different department owns the issue, ask for a documented transfer and retain the original complaint reference alongside the new one.
Respond to relevant requests for missing information. If a document is unavailable, explain why and identify alternative evidence. A statement that you have already supplied everything is less useful than pointing to the exact attachment and page. Keep a copy of each version submitted so a later reviewer can see what was available at each stage.
4. Build an evidence file around the disputed decision
Collect the agreement or offer in force at the relevant time, the affected statement, transaction receipt and correspondence. Identify which sentence or calculation you say was incorrect. A later advertisement or a friend's account terms may not establish what applied to your own product.
Use a simple event table with date, event, evidence and significance. For a disputed fee, show the agreed condition, what occurred and the charge. For a missing transfer, show the instruction, confirmation and account entries. Avoid stating that an unexplained result proves deliberate misconduct when the evidence currently establishes only a discrepancy.
Redact unrelated transactions from copies where that can be done without hiding relevant context. Keep originals securely. Do not send passwords, authentication codes or complete security credentials in a complaint attachment. If the bank needs identity verification or account access, use its verified process rather than replying to an unexpected message asking for sensitive details.
When someone assists you, arrange the authority the bank or OBSI needs to discuss the account. Shared household finances do not necessarily authorize one adult to access another adult's records. Clarifying representation at the start prevents a valid complaint from stalling over consent.
5. Explain the remedy with a transparent calculation
Separate the principal disputed amount from related fees, interest and other losses. State how each figure was calculated and what evidence connects it to the alleged error. A total with no explanation makes it harder to distinguish a correctable account entry from a claim needing additional assessment.
For example, if a charge appears twice, identify both dates and amounts, then subtract any reversal already received. If the bank corrected the duplicate but a related interest charge remains, update the complaint to that remaining issue. Do not keep demanding the original total as though the partial correction never happened.
Describe practical consequences accurately. A missed payment, time spent resolving the issue or inconvenience may be relevant context, but attaching an arbitrary hourly rate does not establish an entitlement to that sum. Ask for the outcome you consider reasonable and explain it without presenting your calculation as an already determined legal award.
6. Recognize when external escalation becomes available
Under FCAC's current guide, you may contact OBSI at the earlier of more than fifty-six calendar days after first complaining to the bank, or the bank providing its detailed written response and closing the file. You do not need to wait for day fifty-seven if an unsatisfactory final response has already closed the bank's process.
Read the response carefully. Is it a request for documents, a progress update or the bank's final position? Save the whole letter, including the date and escalation information. If the language is ambiguous, ask whether the bank considers the complaint closed, while remaining alert to the applicable outside deadline.
A reply saying the issue is complex does not prove that you agreed to wait indefinitely. Keep the original complaint date and the latest status. When escalating, explain whether the basis is an unsatisfactory final response or the elapsed bank-handling period. These are alternative triggers, not requirements that must always both be satisfied.
7. Submit the OBSI complaint within its own time limit
OBSI's published process gives consumers 180 days after the firm's final response to bring the complaint to it. Preserve the written response and when it was received. Do not leave submission until the last possible day while waiting for a further informal conversation.
Provide the institution's name, the first complaint date, its response, the remaining disagreement and the remedy sought. A concise cover note should direct the reviewer to the important documents. If the bank has not provided a final response after the relevant period, explain that and include proof of the original complaint and follow-ups.
Keep the submission confirmation and OBSI reference. A reference confirms receipt, not necessarily that every issue falls within its mandate. If OBSI asks for clarification, connect your answer to the existing case. Do not open multiple versions of the same dispute in an attempt to obtain a faster result.
8. Check mandate and court deadlines separately
OBSI's consumer FAQs identify situations outside its mandate, including an already settled dispute or a matter before the courts. They also explain that eligibility depends on more than dissatisfaction with a fee or decision. Describe any settlement or legal proceedings honestly when submitting the case.
Its limitation-period guidance explains a separate six-year rule: the complaint must have been raised with the firm within six years after the consumer knew or reasonably should have known of the problem. That is not a general six-year deadline for suing a bank in every province.
Court limitation periods and OBSI's complaint deadlines are different. If legal action may be necessary, obtain advice about the applicable provincial or other rules in time. Do not assume that an internal complaint or external review automatically suspends a court deadline. Ask about any relevant written limitation agreement rather than inferring one from an open case.
9. Participate in the review and assess the outcome
OBSI obtains consent to communicate with the firm and reviews both sides' information. Its process can lead to a recommendation, settlement discussions or an explanation that compensation is not warranted. Keep requests and responses organized, and identify new evidence clearly rather than repeatedly sending an unchanged bundle.
A useful reply to an assessment identifies a particular factual error or omitted document. Explain why it matters to the result. Disagreeing with the conclusion is understandable, but a precise response is more useful than restating every earlier allegation. If the assessment recognizes only part of the claim, separate that accepted part from the unresolved remainder.
OBSI describes its recommendations as non-binding and publishes firms' refusals in appropriate cases. It does not promise a guaranteed payment or a regulatory fine. FCAC supervises compliance and provides complaint-process information, but it does not resolve individual compensation disputes. Sending the same demand to FCAC does not convert it into an award.
Before signing a settlement release, check the covered issues, payment amount, timing and effect on further claims. Obtain advice if the terms are unclear or substantial rights are involved. Once a payment or correction is promised, verify the actual account entry. An agreement in principle and money received are different stages.
10. Test the file against a partial-resolution example
Suppose a bank charged a fee you say contradicted a written account offer. You complained, supplied the offer and later received a credit for the fee, but related interest remains. The external file should acknowledge the credit and identify the interest calculation still disputed. It should not present the bank as having done nothing.
Attach the offer, the original charge, the complaint acknowledgement, the credited statement and the bank's explanation of the remaining amount. State whether the final letter addressed interest or only the principal fee. If a representative later promised to reconsider, preserve that message while continuing to track the final-response date and OBSI deadline.
This format lets a reviewer distinguish three questions: whether the initial charge was justified, whether the correction was complete and whether the complaint was handled appropriately. The questions may lead to different findings. Keeping them separate also prevents a disagreement about service quality from obscuring a small, demonstrable arithmetic error that could be corrected immediately.
Five common questions
Must I finish every internal level before contacting OBSI?
Follow the bank's process, but preserve the fifty-six-day clock and any final written response. FCAC identifies the earlier of the elapsed period or a detailed response closing the file as the external escalation point. A new internal reference does not erase your chronology.
Are the fifty-six days business days?
No. The bank-handling period described by FCAC is calendar days. Keep actual dates and distinguish it from any shorter callback promise or another institution's different complaint timetable.
Does OBSI handle every provincial credit union on the same timetable?
No. This guide addresses banks and federal credit unions. Check the institution, participating status and applicable process; provincial credit unions and investment firms may have different periods and requirements.
Will FCAC order the bank to refund my money?
FCAC explains consumer rights and supervises compliance, but does not resolve individual complaints. For a personal remedy, use the bank's process and eligible OBSI escalation, while considering other options where appropriate.
Can I stop making loan payments because a complaint is open?
Do not assume an open complaint changes the payment agreement. Ask how disputed amounts will be handled and obtain any arrangement in writing. If payment difficulty is urgent, raise that separately rather than waiting for the review to finish.
Final file check
Retain the first complaint, acknowledgements, account terms, relevant statements, evidence index, final bank response, OBSI submission and outcome. Record partial corrections as partial and unresolved issues as unresolved. That single file supports a coherent review without inflating a promised credit into a completed payment or losing the deadline among repeated conversations.
