Even if they did, won’t they get a lot of false positives because of a large amount of it being sprayed hemp buds that are legal as hemp? Also, I know a lot of dispensaries get their stock like vape pens and such delivered this way already. How does that all work?
The absolute best is flying with weed inside Canada. Accidentally bought too much on your trip? Not a worry
I still hate that you can buy weed in Ontario and you can buy weed in New York, but bringing it across the border gets you arrested.
