Trailer Import Process?

Has anyone imported a cargo trailer with them when moving from USA to Canada?

I’ve looked around and the documentation of exporting a trailer is rather sparse or non-existent. I’m looking to export a small 5x8 cargo trailer that I’ll be towing with my car.

When I contacted the Customs broker, they told me that an ITN is only needed for self propelled vehicles and since a trailer isn’t self propelled one isn’t needed.

If anyone can share their experience with exporting and importing a trailer that’d be super helpful.
