With roots in the Indigenous community, Idle No More began in November 2012 as a protest against the introduction of Bill C-45 by Stephen Harper’s Conservative government. Formally known as the Jobs and Growth Act, this omnibus legislation affected over 60 acts, including the Indian Act, Navigable Waters Protection Act and Environmental Assessment Act. Idle No More activists argued that the Act’s changes diminished the rights and authority of Indigenous communities while making it easier for governments and businesses to push through projects without strict environmental assessment. The movement quickly gained supporters from across Canada (and abroad), and grew to encompass environmental concerns and Indigenous rights more generally.
