I would imagine importing a truck to Canada is the same as a motorhome. I imported the motorhome in 2017. It was a bit of a hassle. I used an import broker for most of the paperwork but needed to supply them with a bill of sale, clearance docs showing that all recalls had been done ( really hard to obtain) a letter from the manufacturer stating that speedometer read in kph, and that daytime running lights were operational. After the border where you pay the taxes etc you had a short window to get a federal inspection done (cdn tire for $125 and a days time) and then present the vehicle for inspection at the provincial dmv. I saved a few $ buying in the USA but it was a hassle i won’t do again.
