Canada nationally legalized the possession of cannabis in various forms about 2 years ago. I just noticed that my latest home-owner's insurance policy now covers loss/theft cannabis products and plants.
I'm going to have to review my insurance to see if covers "Mysterious Disappearance" losses like yours does. Could be handy if I start forgetting where I put things.
Yes, it's not clear what happens if your car mysteriously disappears from the parkade. This could easily happen if you've been using too much cannabis.
