Were you told that you would need to get an inspection to have the trailer CSA approved? I found a news article that states that the RVIA seal from the US is accepted in Alberta. I think that it would mean an inspection is not required.

Here is the link. Within the aticle is a link to the Vehicle Equipment Regulations from the Alberta Government. On page 51 section 102(1) it to says that the RVIA seal is accepted. I am going to ask my insurance Co. this week but I think an inspection isn't needed.
