There is no such law
The law of Canada prohibits making and distributing Unauthorized copies, and various other acts that infringe copyright, None of its provisions prohibit reading or watching unauthorized copies. In this regard it is the same as US law and the copyright law of most countries.
If you make a temporary copy (say in your computer's cache) while reading or watching, that might be an infringement if the source copy was unauthorized (section 29.22 (1) permits this if the source copy was legally obtained). But when done for personal use, such infringements are almost never the basis ofd a lawsuit. Note that in Canada, as in the US, copyright infringement is not a crime if not done for commercial purposes, only a tort allowing the owner to sue and possibly collect damages.
In the Copyright Act of Canada, section 3(1) specifies the rights that make up copyright as:
For the purposes of this Act, copyright, in relation to a work, means the sole right to produce or reproduce the work or any substantial part thereof in any material form whatever, to perform the work or any substantial part thereof in public or, if the work is unpublished, to publish the work or any substantial part thereof, ...
That section goes on to specify a number of specific rights, but none of them include any right to control who watches a movie or other audio-visual work, who listens to a sound recording, or who reads a written work.
Section 27 (1) provides that:
It is an infringement of copyright for any person to do, without the consent of the owner of the copyright, anything that by this Act only the owner of the copyright has the right to do.
Section 27 (2) provides that:
It is an infringement of copyright for any person to
(a) sell or rent out,
(b) distribute to such an extent as to affect prejudicially the owner of the copyright,
(c) by way of trade distribute, expose or offer for sale or rental, or exhibit in public,
(d) possess for the purpose of doing anything referred to in paragraphs (a) to (c), or
(e) import into Canada for the purpose of doing anything referred to in paragraphs (a) to (c),
a copy of a work, sound recording or fixation of a performer’s performance or of a communication signal that the person knows or should have known infringes copyright or would infringe copyright if it had been made in Canada by the person who made it.
Section 27 (2.3) provides that:
(2.3) It is an infringement of copyright for a person, by means of the Internet or another digital network, to provide a service primarily for the purpose of enabling acts of copyright infringement if an actual infringement of copyright occurs by means of the Internet or another digital network as a result of the use of that service.
Section 29.22 (1) permits making a copy for personal use if the source is a legally-obtained, non-infringing copy and it 9is used only for private purposed and not distributed. This section would not apply if the source is a pirated copy.
