We'll welcome you up here!
I've lived in NWT, northern Quebec, Alberta, and BC is home. Mildest winters are near the southwest coast, if that matters to you.
Without a medical permit we can have 4 plants per household. LOL. No-one seems to care.
I've never heard of them checking home growers. They have their hands full with commercial growers.
A friend lives on a hobby farm with a few animals and has a bunch of outdoor plants plus his indoor plants all summer long. I'm jealous (and grateful) in my city townhouse with a little tent.
