Buying used audio equipment in peron in Canada

Anything to declare is the question you will be asked. I don’t think I have ever said yes... as I never brought anything back. But I assume as long as you don’t lie there will be paperwork to fill out and money to be paid.

I sent my bicycle to Canada once (wrong way for you). The bicycle shop got a bill from Canadian customs for 35% the value of the bike... it took a lot of paperwork and affidavits to show I owned it... sent it there and rode it out of the country. 

Personally, I would send it back and let FedEx or the company act as exporter so you don't end up with the paper work. 

Personally, I don't lie to the government or anyone else for that matter. 

To  be totally prepared, make sure you have a County of Origin Certificate, and a bill of sale.  You may pay a small duty but hey, you just got $1.47 CDN for your US $1.00.  🤣

I drove a pair of UK manufactured ProAc speakers through U.S. Customs on the border between British Columbia and Washington state. The Customs agent had absolutely no idea how to deal with the situation. She spent at least fifteen minutes looking through lists of equipment trying to match what I had with something in their lists. She finally settled on a figure that had absolutely nothing to do with either the original cost or what I was paying for them.I paid it and fled.

If you declare it, the taxes are the same as shipping it.  If you don't declare it, it is a federal crime but clearly not a problem for many forum members.
