You may only be earning a minimal amount as a profit on your rental property, but CRA still requires you report this.
You will report the "Gross Income" as the actual amount you received from your tenants ($1,100 x 12).
Then you will report your expenses. These include:
- Mortgage Interest,
- Utilities
- Property Tax
- Insurance.
