Just got a reply back from Evike regarding the G&P Pro Kit (assembled G&P metal body with mechbox, motor, and pistol grip) they have:
Thank you for contacting Evike.com.
I believe we can attempt to ship it to Canada however we cannot say there would be no issues with it. We have found that ultimately it comes down to the customs representative who receives your package.
Please let me know if you require further information.
