I can see where some might question the registration. The .com had been developed a long time, so the .ca registratant assuming they'd want to expand to Canada one day.
But in defence of it, there are a LOT, as in like 5000+ {something}box.ca registrations, there is an entire industry of curated box monthly delivery services. IMO it is easily arguable that a curated periodic box delivery service of health supplements or products would have completely been a generic and fair use concept for registering the domain.
