If your use is not permitted by a license, or one of the exceptions in the Copyright Act, you will need to ask for permission. The permission must come from the copyright owner so the first step is to identify who the copyright owner is and whether there is an organization that represents the owner.
If the copyright owner is easily identifiable and locatable, simply email or write to them, explaining how and why you want to use the work and requesting permission. The permission should be in writing so that there is evidence of what was agreed to between you and the copyright owner. You should also keep a record of who gave the permission, what was permitted, the date, and how to contact the person who gave the permission. Leave plenty of time for this process, since you can't control how quickly the copyright owner might respond.
There are a number of copyright collectives which can give you permission (in the form of a license) on behalf of the copyright owner to use their work. So, for example, if you want to use music and your use does not fall within any of the Copyright Act’s exceptions, you may be able to obtain permission from copyright collectives such as SOCAN, Canadian Musical Reproduction Rights Agency (CMRRA) or Re:Sound that administer copyright in music.
Remember: Copyright owners have the right to say no, charge a fee or impose conditions on the use of their work.
