The only effective enforcement is us voting with our wallets anyways.
Plus standardizing is also kinda pointless cuz people are drawing their own lines. Like if you live near a Canadian manufacturing plant that makes an American branded product you'll probably be more inclined to purchase those brands that are at least produced here, if not fully owned.
Meanwhile others are going eschew everything not 100% Canadian.
I think naming and shaming brands that deceptively adopt Canadian branding is the best way forward.
