Search CIPO's Canadian Trademarks Database for anything filed after January 22, 2025.

This shows what is on the Canadian trademark register and what looks or sounds similar. It is not legal advice and not a clearance search: it cannot say whether a name is safe to use or would conflict with another mark. A trademark agent can.

Register as of January 22, 2025: CIPO's latest public data release (Open Government Licence – Canada). Marks filed or changed since then are not here yet. Check the current record on CIPO's own database before relying on it.
