Hmm. Something alliterative is always fun.
"Try Canadian Tuesday,’ ‘Made in Canada Monday.’ Though using a day in the name implies it’s a particular day thing.
If you don’t want to use a specific day, could do something like ‘Weekly Northern Novelties,’ ‘The Maple Market Mission’ or ‘Buy Canada Challenge’ or something like that.
Yeah, lately I’m finding I need to make trade-offs about what is important to me. Ideally I’d want Canada-owned/Canada-made AND less single use plastic, but sometimes I need to settle for something I can find, at least for things like dental floss where it’s a hygiene thing. (Though nice-to-have stuff I can just not buy it at all.)
