Traffic delays are possible on Highways 401 and 403 on Monday due to a rolling blockade.
According to OPP, "protest activities may periodically delay or interrupt the normal flow of traffic on area highways in Middlesex, Oxford, and Brant Counties."
OPP did not specify what the protest is for, but posts on social media indicate the rolling blockage is in support of British Columbia's Wet’suwet’en nation's fight against a pipeline.
The OPP say they will work to restore traffic flow in the safest manner possible. The police also say they will "work with those who may organize protest events to provide a safe and peaceful opportunity to exercise their lawful rights while minimizing the impact on the traveling public, where possible."
Drivers are urged to check in advance for road advisory information and monitor local media for the latest updates.
