Side note for lurkers in Alberta who might care: At-home rapid tests can be had at any pharmacy for free now, just show them your health card, or your DL, or a picture, or pretty much anything; my pharmacist told me they'll take anything for anyone who wants one, it's just that they're supposed to keep track because you're only allowed one every two weeks (to try to stave off the weirdo hoarders.) But on the other hand, they want to give 'em to anyone who wants one. They're good for five tests.
