When an employee files a human rights complaint against an employer, the relationship between those parties enters a fundamentally altered state. The complaint itself represents an assertion of rights protected under law, and Canadian human rights legislation across all jurisdictions recognizes that this assertion must be protected from interference. Retaliation prohibition exists precisely because the entire human rights system would collapse if employers could punish workers for seeking its protection. The concept operates on a straightforward premise: an employee who experiences discrimination or harassment must be able to report that conduct without fear that doing so will make their situation worse. This protection extends beyond the person who files the complaint to encompass witnesses, individuals who assist complainants, and anyone else who participates in the complaint process in good faith.
The legislative foundation for retaliation prohibition appears in every provincial and territorial human rights code in Canada, as well as in the federal Canadian Human Rights Act for federally regulated employers. In British Columbia, the Human Rights Code prohibits retaliation against any person who files a complaint, gives evidence, or assists in a complaint under the Code, as of the date of authorship. Alberta's Alberta Human Rights Act contains similar provisions protecting complainants and participants from adverse treatment. Ontario's Human Rights Code explicitly prohibits reprisals for claiming or enforcing rights under that legislation. Saskatchewan's Human Rights Code mirrors this approach, as does the legislation in Manitoba, the Atlantic provinces, and the territories. Quebec approaches the matter through the Charter of Human Rights and Freedoms, which integrates protection against reprisal into its broader framework governing dignified treatment in employment relationships. The federal Canadian Human Rights Act prohibits retaliation or threats against any person who has filed a complaint, given evidence, or otherwise assisted in a complaint process. What unites all these legislative frameworks is the recognition that the right to seek redress for discrimination must be practically enforceable, and practical enforceability requires protection from backlash.
