In the past few weeks, First Nations groups in Canada have set up a blockade to stop shale-gas exploration in New Brunswick, marched outside the Ontario premier's house to protest high mercury levels and forced a coal-mining company in British Columbia to delay exploratory drilling.

The protests are part of a growing First Nations activism that took root in Canada last winter with the powerful movement known as Idle No More. The mass protests, which drew thousands to snow-lined streets across the country, have gone quiet in recent months, but activists insist the fight is far from over.

On Monday they will try to take that message to the wider public, with 50 events planned across Canada and the United States, along with an estimated 10 other countires, including England and India. That day marks the 250th anniversary of the British Royal Proclamation, which led to the founding of Canada.

"We must collectively send a clear message that our movement will not stop intervening in Canada’s attempts to conduct business as usual," says a statement from the group declaring Oct. 7 a Day of Action.

Activists are now hoping for a reset on the relationship between aboriginal and nonaboriginal people. Monday coincides with the arrival of the United Nation's special Rapporteur on Indigenous Rights, who will begin a week-and-a-half-long tour investigating the plight of the country's aboriginal peoples.

Planned events for the day range from a flash-mob round dance in Saskatoon, Saskatchewan, to a picnic in Toronto to a protest on Parliament Hill in Ottawa.
