Canadian Prime Minister Mark Carney's economic overhaul is facing resistance from organized labour over proposed limits on the right to strike. The clash centres on Bill C-39, which would give Ottawa clearer powers to intervene in legal strikes and lockouts in federally regulated workplaces. The largest unions, including CUPE, have vowed to defy the bill if it passes without amendments.
Key Facts
- Bill C-39, announced last month, would give Ottawa clearer powers to intervene in legal strikes and lockouts in federally regulated workplaces.
- CUPE National President Mark Hancock said the union's 800,000 members want to be part of 'Team Canada' but questioned the cost.
- Ottawa used Section 107 of the Canada Labour Code eight times since 2024 to intervene in disputes involving airlines, railways, ports and Canada Post.
- US President Donald Trump has imposed steep tariffs on Canadian goods and repeatedly threatened to make Canada the 51st US state.
Union Opposition
Canada's largest unions have come together against the proposed changes to strike rules. CUPE's national executive voted to defy the bill's proposed limits on the right to strike if it passes Parliament without amendments. CUPE National President Mark Hancock credited Carney's handling of Trump but asked 'at what cost?' regarding the bill's labour provisions.
Legislative Context
The controversy centres on Section 107 of the Canada Labour Code, which gives the Labour Minister broad powers to step into disputes to maintain 'industrial peace'. Beginning in 2024, Ottawa used the provision eight times to intervene in disputes involving airlines, Canada's two largest railways, three major ports and Canada Post. The provision was used again during the Air Canada dispute in 2025 when flight attendants went on strike.
