Publishers usually allow self-archiving of a scholarly work in an institutional repository. Limitations may exist on what version of a scholarly work you are allowed to upload (e.g., Published Version, Accepted Manuscript/Post-Print, or Submitted/Pre-Print version), and when you are allowed to upload it (i.e., after an embargo).
Consider using the Canadian Author Addendum to Publication Agreement to secure self-archiving rights (if they don't already exist in the publication agreement) when your future articles are accepted for publication.
