It's an American law which implements a certain part of the WIPO Copyright Treaty, which is indeed in force in Canada (since 2014) with a local implementing law, as well as in the European Union and many other countries worldwide:
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.
