I don't know about Canada., but in this region of the world they don't give a rat's a.. about a bicycle, new or old.
I have been biking/flying back and forth for over 30 years in the Asean region ,they don't care at all.
The only thing that has changed over the decades is, that while many airlines would accept unboxed bicycle, most, if not all ,require you to box it up now. A major hassle.
