Let's review one of the court documents because it has a very important detail. https://cdn.ca9.uscourts.gov/datastore/opinions/2016/08/26/1... > Defendant Michael Norman Hallatt purchased Trader Joe’s-branded goods in Washington State, transported them to Canada, and resold them there in a store he designed to mimic a Trader Joe’s store .

> he designed to mimic a Trader Joe’s So what? The mimicry occurs in Canada, where Trader Joe's apparently does not operate. I thought the whole point of trademark law was to prevent customer confusion, not to give a party property-like rights to some retail "style." I'm really surprised this is an issue for the US courts at all, and that they didn't refer Trader Joe's to the Canadian court system.
So says Wikipedia:
> Trade dress is a legal term of art that generally refers to characteristics of the visual appearance of a product or its packaging (or even the design of a building) that signify the source of the product to consumers.
IANAL but selling Trading Joe's products and those alone in a store that looks like Trading Joe's could at least give rise to a trade dress claim.
As to extraterritoriality, NAFTA applies, trademarks are recognized across the border.
