Hi @teenytrinkets - thanks for your patience on this topic while I'm working to have this reviewed.
From what I've been able to find out this is related to Covid filters, and should only be blocking the ability for an item to show up in search on sites other than the one on which it was listed. That is, it won't keep you from listing the item and won't pull the item down.
While I wait for more information on any workaround or resolution, you could consider manually listing items on both .com and .ca to make sure they show up on both sites. Just make sure that they don't offer shipping to either country (meaning don't offer shipping to Canada on your .com listing and vice versa). You'd need to manage quantity numbers so you don't end up oversold too.
I know that's not a particularly elegant solution, but it will at least allow you to get items up and out there.
