Quebec TSO vs Ontario mandatory overtime: not the same thing.
Anyone who publishes a single national mandatory-overtime percentage for Canadian nurses is conflating two different legal regimes. Quebec's TSO sits under the Code du travail and the FIQ collective agreement; refusing can trigger an OIIQ professional-conduct complaint. Ontario's 'mandatory' overtime under ONA contracts is grievable. The figures, the recourse, and the political pressure points all differ.

Frequently asked
- Is mandatory overtime legal for nurses in Canada?
- Different things in different provinces. In Quebec TSO is structured under the Code du travail and the FIQ collective agreement; the OIIQ's professional-conduct duty (Article 43) creates a double-bind where refusing can trigger a professional complaint. In Ontario 'mandatory' overtime under ONA contracts is grievable.
- Which province has higher actual mandatory overtime?
- Not directly comparable. Quebec measures TSO as a share of union-member hours (peaked at 2.75% in Saguenay-Lac-St-Jean, January 2023). Ontario measures via Statistics Canada Labour Force Survey hours-worked (8.2 hrs/wk average overtime in 2022, record high).
- What changed after Bill 124 was struck down in Ontario?
- Reopener arbitration awarded 0.75% (2020), 1.0% (2021), 2.0% (2022) on top of the original 1% caps — RNAO calculated this as 'not nearly enough' to restore real-wage purchasing power.
