For sign-based notice under Ontario’s Trespass to Property Act, signs must be clearly visible in daylight under normal conditions from the approach to ordinary points of access.
At a glance
- The Act specifically addresses visibility of signs from ordinary points of access.
- Access-control procedures should align with the property’s actual entrances and traffic flow.
- A security patrol can note damaged, missing or obstructed signs, but the occupier remains responsible for the property’s notice strategy.
Short answer
The official rules establish the baseline, but the correct operational response still depends on the property, the applicable law and the facts. The safest approach is to define the procedure before the issue occurs and avoid adding powers, guarantees or requirements that the official sources do not establish.
Questions to confirm
- Which entrances are actually used by visitors, workers and vehicles?
- Can a person see the sign before entering?
- Are temporary construction or delivery entrances covered?
Picture this at your property
A construction project opens a new temporary driveway but the existing notice remains at the old gate. The property’s access and notice arrangements should be reviewed as the site changes.
The value of the example is the decision process: identify what is known, what remains uncertain, who has authority, and what information should be preserved for follow-up.
Practical takeaway
Treat the answer as a starting point. Confirm the current rule that applies to the organization and property, then document the procedure the people on site are expected to follow.
