This document provides an overview of key differences between employment and labour law in Canada compared to the United States. It notes that employment is primarily regulated at the provincial level across Canada's 13 jurisdictions, with some industries also governed by federal law. Major differences include the lack of an "at-will" employment doctrine, stronger worker protections like notice or severance requirements, the recognition of constructive dismissal, and more limited enforceability of restrictive covenants. The document also summarizes regulations around leaves, termination, human rights, unionization, and occupational health and safety.
