As far as customs goes, I doubt they will care as long as you declare it and are willing to pay duty on it. Lots of canadians purchase appliances in the states.

The stove I have right now has doors that get hot also, when my kids were little they learnt quickly to not touch the doors when the oven was on.

There are tons of posts on the appliances forum about this, including US customers purchasing them in Canada. So a google search with "garden web" as a part of it, and you'll find more info than you want to know.

I've never seen one on the floor at the Costco stores I've been to here in Alberta. Just seen them on-line for order. I would call the stores and see if they have them in stock first.

I shop at the Still Creek location and have never noticed any appliances on the floor at all. However, there may be an appliance booth (There are window covering and floor covering booths) that I just have never noticed. Sorry I can't be of more help.

Do you have any friends in Canada? You might be best off having them order it for you and have it delivered to their place for you to then pick up.

They're HEAVY. And there's no difference between having it in the back of a pickup truck or in the back of a minivan in terms of being asked questions at the border. I trust you weren't thinking you might simply pass through back into the US with a giant 'thing' in the back of a minivan covered with a blanket? Big enough to house a couple grown men?

Frankly having it in a pickup truck where it can be easily accessed and inspected by your friendly Homeland Security folks might be your best bet for an easy homecoming.
