On Monday, Poilievre promised to use the notwithstanding clause to impose consecutive life sentences on multiple murderers. The Supreme Court of Canada ruled in 2022 that imposing consecutive life sentences violates an offender’s Charter rights.

“One of the last remaining restraining or constraining conventions about the notwithstanding [clause] is that no federal government has used it. Now we have someone enthusiastically proposing that. That’s major,” said Axworthy, who is now chair of public policy at the University of Toronto’s Massey College.
