FYI - Challenge, Veloflex, FMB and Vittoria all sell a Roubaix model tire (which I assume are not licensed). That has more in common with wheels than a bicycle frame. There is a bottle cage model called the roubaix. There are Roubaix cycling clothing models. There is a Roubaix shoe cover.

Holding a trademark and having it enforced in a courtroom are different. I acknowledge I'm no expert on Canadian law, but this is hardly clear on either side.
