Importing a Canadian vehicle into the United States, if the vehicle wasn't specifically intended for the US, is a slow and expensive process.
Your first, large, hurdle is the EPA:

If that doesn't scare you off, then you can address the DOT import process:

The next step is finding an NHTSA registered importer:

Finally, you'll owe a 3.4% duty on the sale price.
Yes, it can be done. But is is both expensive and time-consuming.
