Not sure about their policies to Canada, but the online web stores Erogenos.com, Mensuas.com, Skiviez.com, and Be-Brief.com all have excellent 365 day free return policies. They all have the same address so I think it’s one company that operates all the different sites each with different promotions and marketing. But I’ve been buying from them for 3 years and never had a problem with a return. I always buy extra pairs to try on and only keep the ones I like.
