HELP NEEDED

[DAZ]

H2 owner needs help! I live in the UK and am on my second H2 which is an '05 SUV in black from my local Hummer dealer in Manchester. The problem I have is that I am moving to Saskatchewan, Canada and want to take my vehicle with me but transport Canada says it is inadmissable because it does not have the federal safety standard sticker on the drivers door.
The vehicle is built in the USA and according to my dealer the vehicle is built to full federal saftey standards (like any other H2 that rolls off the production line), and is to Canadian spec. Apparently to get my vehicle into Canada I need to obtain a letter from GM stating that it is built to Federal standards but I can't seem to get hold of the correct person at GM, and no-one is willing to help. Does anyone out there know the correct contact at GM to help a loyal customer. Many thanks from a loyal H2 owner.
