What is the main purpose of employment law in Canada?

Employment law in Canada differs variably jurisdiction to jurisdiction. Although the common law governs employment relationships in all jurisdictions across Canada (except Quebec, which is governed by a civil law system), each jurisdiction/province has specific labour and employment law statutes (such as employment standards, human rights, occupational health & safety, etc.). The main purpose of employment law in Canada is to govern the legal and contractual relationship of employers and employees, and to provide safeguards for vulnerable employees while protecting the legitimate business interests of employers.
