No Canadian province has a fatigue or hours-of-work law written for teachers. Ontario goes further: teachers are expressly excluded from the Employment Standards Act rules on daily and weekly hours, rest between shifts, weekly rest, eating periods and overtime, so no statutory hours ceiling applies to teaching work at all. What limits workload in practice is the collective agreement - class-size and preparation-time terms, and locally negotiated workload accords - which vary board by board. Safety law still applies to every school board as an employer, and fatigue must be managed under the duty to take every precaution reasonable in the circumstances.
Qui la réglemente
No dedicated fatigue regulator covers teaching. Provincial education ministries and school boards set the framework; the province's labor ministry and workers' compensation board enforce workplace safety and injury claims; and the practical limits on class size and preparation time come from collective agreements and workload accords negotiated by teacher federations such as OSSTF and ETFO.
Vos obligations
Your obligations sit in three places. The provincial occupational health and safety act applies to school boards like any other employer: assess hazards, train staff, keep a written health and safety policy, and take every precaution reasonable in the circumstances - fatigue included. The collective agreement binds you on class size, preparation time and supervision duties, and because Ontario teachers have no statutory hours ceiling those terms are the workload limit. Your school bus drivers are separately subject to hours-of-service limits - provincial rules for runs inside one province, federal rules for interprovincial or cross-border work.
Conséquences
Breach of a workload accord or a collective-agreement workload clause is a labor-relations matter: the federation grieves it and an arbitrator can order compliance and, in some cases, compensation. It is not a safety prosecution. A fatigue-related injury or incident runs on a different track - the provincial labor ministry can issue compliance and stop-work orders and prosecute the board, and directors and officers can be charged personally. Failing to accommodate a diagnosed sleep disorder can bring a human rights tribunal order for damages, lost wages and reinstatement. Hours-of-service breaches by your bus drivers attract roadside penalties and damage the operator safety record the province tracks.
Sanctions
Ontario's occupational health and safety maximums, as they stand in 2026, are $2,000,000 per offence for a corporation, $1,500,000 for a director or officer and $500,000 for any other individual, with up to 12 months' imprisonment for individuals; a corporation convicted a second time within two years of an offence causing death or serious injury faces a minimum fine of $500,000. Other provinces set their own scales. No teacher-specific fatigue penalty figures exist.
Antécédents
No Canadian court, coroner, investigator or regulator has published a finding linking fatigue to an incident in education. The duty to manage fatigue still sits within the general duty in federal and provincial occupational health and safety law.
