I live in Alaska and drive from Southeast Alaska to Interior Alaska on a regular basis. Is there a similar device which will work in Northwest Canada?
According to their coverage map (http://www.findmespot.com/en/index.php?cid=109) you can get this device for coverage where you are looking for it. If you are looking for something less expensive you can get one of their less expensive models. I have the SPOT Personal tracker and it tracks and send OKs just fine. I think it is around $100 plus services.
I used this device in Northern Canada while floating 600 miles on the Yukon River from Johnson's Crossing to Dawson City. It worked flawlessly.
