Frequently Asked Questions

1. Why do we need Emergency Detour Routes (EDRs)?

To provide drivers with a pre-determined route when a provincial highway is closed.

2. When are emergency highway closures necessary?

These unscheduled closures are required when a highway is physically impassable or when emergency work cannot be performed in traffic.

3. How long will the Emergency Detour Route (EDR) be activated?

The duration of a highway closure will vary depending on the extent and nature of the incident. Most incidents normally require approximately two to three hours to clear.

4. Who decides when the highway should be closed or opened?

The police have the authority to close highways. An officer at the incident will determine when to reopen the highway and deactivate the Emergency Detour Route (EDR).

5. I have a large truck carrying an oversized or overweight load. Can I use the Emergency Detour Route (EDR)?

No. Oversized or overweight loads travel under permit-defined routes and are not permitted on any other route. The police will direct you to park in a safe location on the highway until it reopens.

6. I live in an area that the Emergency Detour Route (EDR) goes through. How will I be affected?

While the Emergency Detour Route (EDR) is activated there will be an increase in traffic. This might also include more trucks. Local police or municipal staff might be present to direct traffic at key intersections and monitor the use of the Emergency Detour Route (EDR).

7. How are the Emergency Detour Routes (EDRs) selected?

Emergency Detour Routes (EDRs) are developed by the municipality with the MTO and the police. They are based on several factors including travel time and a route's ability to efficiently accommodate increased traffic volumes.
