Marchers, including members of several southwestern Ontario First Nations, converged just short of the busy international bridge's entrance today, with many carrying flags and signs calling on the federal government to listen to aboriginal concerns.
There is a line of transport trucks about a kilometre long, waiting to get by.
Police say some traffic is blocked from getting onto the bridge to the United States (northbound on Huron Church Road) but another entrance (at Wyandotte Street) remains open.
The company that owns the bridge says it will open a nearby parking lot in order to move the marchers off the road and allow the trucks to pass.
Organizers have said the protest would not be a blockade but a peaceful march that's not part of the Idle No More protests that have been held across the country in recent weeks.
The Idle No More movement began last month in protest of a federal government omnibus bill that First Nations groups say threatens their treaty rights set out in the Constitution.
