The right to strike is guaranteed in the Canadian Constitution and the Charter of Rights and Freedoms.
In Saskatchewan Federation of Labour vs. Saskatchewan, the Supreme Court of Canada declared the Public Service Essential Services Act unconstitutional with a vote of 5 to 4.
In this particular case the limited amount of public sector workers that were deemed essential and not allowed to strike has been relaxed.
The province of Saskatchewan will now need to reconfigure how they deal with strikes while ensuring essential services remain in place. (reposted from The Dispatch)
