Justin Trudeau met by protesters at Labour Day parade in Hamilton

Grassy Narrows supporters protest against Trudeau government in Hamilton

Liberal Prime Minister Justin Trudeau, Conservative leader Andrew Scheer and NDP leader Jagmeet Singh were all in Hamilton Ont, on Monday to woo workers at Labour Day events.

Trudeau participated in the annual Labour Day parade there, Singh took part in the annual Labour Day picnic, and Scheer attended the Labour Day classic football game between the Hamilton Tiger Cats and Toronto Argonauts.

While Trudeau was marching alongside the Liuna Local 837 union during the parade he was confronted by a group of anarchists, Marxists and indigenous protesters.

The protesters stopped the parade and standoff with security ensued. Many of the demonstrators were carrying water protector signs, and some called for more action for sufferers of mercury poisoning in Grassy Narrows First Nation in northwestern Ontario.

The Trudeau government has promised a specialized mercury treatment facility for the community.

He was also jeered by workers who feel he had no place there.

The protesters stood in the parade path, after an impasse of about 45 minutes, Trudeau appeared to leave the event. But he joined the union group again a block later. The protesters continued to follow Trudeau and heckled him until he left.

All three federal party leaders were in Hamilton to gear up for the national election scheduled for this fall.

Grassy Narrows is about 100 kilometres northeast of Kenora.
