Once you have written up your research, don't forget the citations. Unless your supervisor has specified otherwise, it is safe to assume that your citations should be written up in McGill Guide style. The ninth edition of the McGill Guide is available in print at the law library, or you can access it electronically via your personal Westlaw Edge Canada accounts.
If you need a concise refresher to the McGill Guide rules, the law library's guide, Legal Citation with the 9th Edition of the McGill Guide is an excellent resource. The guide includes an overview of the basic rules of legal citation, as well as an interactive legal citation tutorial.
