On Nov. 9, 2023, the Honourable Seamus O'Regan, newly appointed Minister of Labour and Seniors (the "Minister"), tabled Bill C-58 – An Act to amend the Canada Labour Code and the Canada Industrial Relations Board Regulations, 2012.

The bill, which received royal assent on Thursday, June 20, 2024, sets out strong measures to limit the use of replacement workers (or strike-breakers) by federally regulated employers.

Provisions in force since June 20, 2025

As discussed in an earlier BLG Insight on this topic, the final legislation that was adopted is quite similar to the initial bill aside from key amendments, including the scheduled coming-into-force date.

As a result, the provisions governing the use of replacement workers came into force on June 20, 2025.

Unsubstantiated Findings In Workplace Investigations: What To Do When You Can’t Decide

When workplace investigators face difficult decisions, many default to marking allegations as "unsubstantiated" to avoid risk. However, this seemingly safe approach carries significant organizational costs, undermines complainant trust, and often stems from insufficient training in credibility assessment and the balance of probabilities standard.

New AI Safety Standard Relevant To Canadian School Boards

A major U.S. vendor agreement has established a rigorous new AI safety standard for educational technology, prohibiting the use of student data for AI training and enforcing strict data minimization. While the standard does not directly bind vendors in Canada, Canadian school boards can leverage this precedent to demand equivalent contractual protections and strengthen their own AI governance frameworks.
