The DMCA is an American law, which does not apply in Canada or much of the rest of the world.

With all of that said, Canada's legal analogue to the DMCA is a "notice and notice" regime, not a "notice and takedown" regime. The rights holder or their agent notifies the ISP, and the ISP notifies the user without necessarily taking down the content. A court order can be sought to force it offline, and I'd guess (but don't know) that some ISPs will voluntarily cooperate to some degree beyond the legal requirement.
Even if it had needed to rely on DMCA-like concerns, over a hundred countries worldwide are party to the treaty which mandates a law addressing the scope of the DMCA, so enough other countries have such a law. (The details vary and not all such laws mandate a quick takedown of the allegedly infringing content.)
