So, Alberta has used S33 as part of its “Back To Work” legislation for ending the teachers strike. There will be many pixels of virtual ink spilled over this. Much of that will go on breathlessly about how this is “unprecedented”, “shocking”, and so on. Rest assured, none of this is shocking. The UCP has been looking for an excuse to use S33 for quite some time - going back to Jason Kenney, if you have been paying attention. Kenney’s Bill 1 would have become that bill - except the excuse for Bill 1 vaporized.
The UCP is being purposeful. They started musing about S33 to buttress their anti-trans legislation a while ago, but I think they also realized that outside their base, the broader public has little appetite for such a move. This application of it is “temporary”, and addresses events that are directly affecting families (often an easy sell for conservatives who love to spout off about family values).
