Hi Colin,
I had the same problem. I'm in Calgary and I had a heck of a time finding someone to ship up here. But I have my Maverick now!
I ordered through Smarthome.com
They ship to Canada via FedEx. I think it cost me about $85 Canadian for the unit by the time I payed the exchange and the customs fees. It took about 2.5 weeks for delivery, but most of that time it was sitting at Customs Canada in Vancouver.
I think the unit is sold under the brand name "Redi Check", but it is manufactured by Maverick.
