Canadian aftermarket warranty?

[Niagara 325i]

I bought my 2006 325i in Georgia (I lived there at the time) and since importing it into Canada BMW won't honour the warranty (how's that for customer service!). Now I'm trying to sell my car — immaculate, 1 owner, low mileage etc., should be an easy sell — and the lack of warranty seems to be a deal breaker.

Can anyone recommend a Canadian aftermarket warranty company?
