The reminder of my post is PURELY technical. It is in no way telling you whether or not to break the law.
If your connection is not coming from your Canadian ISP, then they cannot track it back to you. How can you be in Canada but not connect from Canada? Three letters - VPN!
With a VPN you can effectively teleport your computer to another country. VPN connections are encrypted, so all your ISP will know is that you are VPNing to some other country, they cannot know what you are doing. Also, the site you download from will see you as connecting from that other country, so they will not know who your real ISP is, so they cannot possibly contact you.
In reality, this kind of law can only work if the copyright holder can see what you are doing. If you download from the web, they can't unless the sharing site decides to share their logs. I do not believe download sites are doing that.
If on the other hand you use a peer-to-peer sharing service, then everyone on the service can see what you are doing, including the copyright holders. Basically - in terms of technical practicalities, this is only a law against peer-to-peer sharing.
I can tell you that if I was in Canada, I wouldn't be put off by this technically futile law.
