In March 2023, the Trademarks Office and Trademarks Opposition Board launched an online service called the Trademark Document Retrieval Service (TDRS) in order to send Office correspondence electronically.
We encourage you to select email as your preferred method to receive trademark correspondence from CIPO.
If you would like to keep mail as your method of correspondence, no action is required.
| Type of client | Options to choose your preferred method of correspondence |
|---|---|
| For trademark agents |
|
| For firm accounts |
|
| For applicants and owners |
|
| For opponents and Section 45 |
|
- If you submit via our online service for agents, your account will be updated in real time.
- If you submit by fax, mail or general correspondence it may take up to 4 weeks for the change to take effect.
