Toronto Electric Commissioners V. Snider - Aftermath

Aftermath

After Snider, the Parliament of Canada revised the Industrial Disputes Investigation Act to restrict its application to federally incorporated companies and federally regulated industries, but also allowed it to be extended to any province by Act of its legislature. Six provinces exercised that option by 1928, and by 1932 all provinces other than Prince Edward Island had done so.

In World War II, federal jurisdiction was restored under the Wartime Labour Relations Regulations, which lasted until 1947. Afterwards, the provinces asserted their jurisdiction, and labour relations subsequently became regulated province by province, with federal authority only extending to federally regulated industries.
