Hundreds of demonstrators are gathered in front of Parliament Hill as part of the series of Idle No More protests taking place across the country.
The Prime Minister is scheduled to meet with First Nations chiefs within the hour as a crowd of protestors show their support for Theresa Spence, chief of Attawapiskat, who is currently on a hunger strike.
Demonstrators began their march from Victoria Island at 11 a.m., and continued to Portage Bridge before heading east on Wellington Street to Parliament Hill where First Nations chiefs addressed the crowd.
Ottawa police are advising drivers to take alternative routes when possible as traffic disruptions are foreseen.
Bay and Kent streets (between Wellington and Queen streets) have also been closed by police.
