Copying material that was produced by persons other than the thesis author may violate the law of copyright. You are personally responsible for ensuring that your thesis complies with Canadian copyright law, and the cIRcle license requires that you confirm that you have done so.

Offers to publish your thesis
You should be aware that students who have graduated may be contacted by publishing companies that have an interest in publishing their thesis. These companies often contact authors directly. You are free to grant permission, but you should research the company first to ensure that it is a reputable academic publisher. There are usually discussions among former students online that can give you an insight into the value of publishing with a particular company.
