What the stamp should show
The mark is a bordered box with the IPPC symbol on the left. To its right: CA, a hyphen, the code Canadian Food Inspection Agency gave the producer or treatment provider, and the treatment code. Producer code formats differ by country, so check the shape of the code against other marks from Canada rather than against a fixed pattern.
IPPC | CA-[producer code] | HT (layout only; the producer code is a placeholder)
Who authorises the mark in Canada
The IPPC country page for Canada lists the official contact point as Canadian Food Inspection Agency, registered on 11 Jul 2018. That body, or the agency it delegates to, registers treatment providers and producers and polices use of the mark. Open the IPPC page for Canada for current contact details.

On arrival in the US or Canada
Wood packaging from Canada entering the United States is regulated under 7 CFR 319.40-3; entering Canada, under CFIA directive D-98-08. Both rely on the ISPM 15 treatment and mark. Once the goods are unpacked, surplus pallets from Canada are yours to reuse, sell or recycle, unless they belong to a rental pool.
