CIBC’s main personal banking customer service line is 1-800-465-2422, available 24 hours a day, 7 days a week. This covers general account inquiries, lost or stolen cards, fraud reports, and most personal banking needs. For CIBC Investor’s Edge, a separate line handles brokerage-specific inquiries.
For complaint escalation beyond the branch or call centre, CIBC has an internal Ombudsman and the independent Ombudsman for Banking Services and Investments (OBSI) as a final escalation step.

Complaint Escalation Path
| Step | Contact | When to Use |
|---|---|---|
| Step 1 | Branch manager or 1-800-465-2422 | First point of contact for any complaint |
| Step 2 | CIBC Client Care Centre (same number) | If the front-line agent cannot resolve |
| Step 3 | CIBC Ombudsman — ombudsman@cibc.com | If Client Care Centre does not resolve within 90 days |
| Step 4 | OBSI: 1-888-451-4519 / obsi.ca | Independent review; free to consumers; final external step |
The Ombudsman for Banking Services and Investments (OBSI) is the external complaint body for CIBC. OBSI can recommend compensation of up to $350,000 for unresolved disputes. Its decisions are non-binding recommendations, but most banks comply. There is no cost to file with OBSI. You must have gone through CIBC’s internal complaint process before OBSI will accept a case.
