Lol no they fucking won't. There's well over 2.2 million (R)PAL holders, damn near every province, territory, jurisdiction, and police force has said they won't do it, nor fund it. There's also an amnesty until the end of October, and if you're in Saskatchewan, you have nothing to worry about.
On the bright side, such draconian and over the top authoritarian threats should make other provinces follow Saskatchewan's lead sooner rather than later. Bravo!
The Supreme Court is also taking another look at this communist bullshit, but I wouldn't hold my breath.
TLDR - go fuck yourself Gary.
