Well...not really sure how to respond to this...it's generally similar.
Canadian "artists" get (for lack of a better word) inspiration from American "artists", who occasionally also derive inspiration from Canadian music. Note the occasionally. For example, maybe American drummers idolized Neil Peart, while he, in his time, idolized several American drummers. Honestly, it's one border. It won't really make as much of a huge difference, although there would be fewer musicians to actually make this music.
