Here is a useful list of Canadian and foreign labour law scholars with links to their free downloadable academic papers.
I put this list together quickly, mostly from the top of my head. I am positive I am missing people who have SSRN pages, so if any come to your mind, please let me know and I will add them. I will keep this entry linked under the Scholarship Page on the top of the blog for easy future access.
