So the only way is to export the vehicle. My question is export to whom ? I should know some one right in US to import vehicle? Can someone import vehicle on my behalf in US?
Are there any dealer who can buy it may be in US and I can export to their address
This is not quite true. There is also the option of destroying the vehicle under CBSA supervision. That is permitted under Schedule VII as an alternative to returning it to the USA.

If destroyed – Supervised by the Canada Border Services Agency (CBSA): a ‘certified copy' of an E15 form, "Certificate of Destruction/Exportation" is required. Appointments must be scheduled in advance by contacting a regional Trade Compliance Division (TCD) office to have a CBSA officer witness destruction, inspect the disposed vehicle on site and confirm the complete destruction on an E15 form. For more information on this procedure, please contact CBSA at 1 800-461-9999 (toll free).
If destroyed – Without CBSA supervision: a certificate from an authorized disposal processing operation (not a recycler) is required. The certificate must include some identifiable reference to the Vehicle Identification Number (VIN), or serial number if none is assigned. In addition, pictures or a video clip recording the destruction process must show the complete demise of the vehicle. Dismantling, disassembly or recycling of parts is not acceptable.
We do not accept dismantling or recycling of parts as proof of destruction.
