If you are single this sounds like it might be an interesting opportunity as long as you find a GOOD place to settle in the US. Much like every province is very different in Canada so are the states.

However keep a few things in mind:

• you will be a foreigner ( make sure you know your rights / or lack there of)
• your employment terms may change immediately from being fairly safe and having severance in Canada in law to changing to at will termination in the US depending on the state and situation.
• find out ALL the details of your company medical coverage and its cost before going, everything will cost you money medically in the US but you might get faster service
• If you are thinking about buying a home find out what the laws are for foreigners on a TN visa.. Also find out what the property taxes are as in some states they are VERY high, while the price of the home is attractive.

Alternatively look into low cost of living places in Canada and consider moving within Canada. You may find that there is a lot of difference in the provinces and major cities.
