At a secondary school in northern Ontario, the Grade 11 French class has had four different supply teachers since September. The regular teacher left for a permanent position in Ottawa; the board has not been able to fill the vacancy. This is not unusual. According to the Ontario College of Teachers, 35% of secondary schools and 24% of elementary schools reported daily teacher shortages in 2023-24. Rural communities, high-needs schools, and specialized subjects (French, Indigenous languages, technological education) got hit worst.
Schools Reporting Daily Teacher Shortages (2023-24)
The OCT certified 8,139 new teachers in 2024. The estimated annual need is 9,600.
A gap of roughly 1,500 teachers per year. And it’s widening.

Annual shortfall: ~1,500 teachers
Demographics explain most of it. Ontario’s teaching workforce skews old, and boomers are leaving in waves: roughly 12,000 retirements expected between 2024 and 2028. That figure doesn’t account for the 30% of new teachers who quit within five years, citing workload and inadequate support. So you lose them on the way in and on the way out.
Retirements are concentrated in the hardest-to-fill specializations. Experienced French teachers, special education resource teachers, guidance counsellors: retiring faster than replacements can be trained. Northern boards are especially exposed; the Algoma District School Board reported in 2024 that more than 40% of its teaching staff would be eligible for retirement within five years. Forty percent. In one board.
Not Enough French Teachers to Go Around
Ontario is constitutionally required to provide French-language education. Finding the teachers to do it? One of the system’s most stubborn problems, particularly in rural Northern and Eastern Ontario, where francophone educators have little reason to relocate.
And it’s not just immersion. Core French instruction, mandatory in elementary schools, is also affected. Some boards have reduced French programming rather than leave classrooms unstaffed: the TDSB cut core French from several elementary schools in 2024, and the Upper Canada District School Board scaled back immersion entry points in Eastern Ontario. Parents in affected communities have organized letter-writing campaigns and delegations to trustees, but the fundamental constraint is supply. There are not enough qualified French teachers to go around.
Special Education Under Strain
Special education gets hit hardest. Students with IEPs depend on qualified special education teachers and educational assistants for modified programming, behaviour support, one-on-one instruction. When those positions go unfilled, a regular classroom teacher with 28 students and no training in autism interventions is suddenly expected to cover the gap.
Nobody asked them.
The Ontario Human Rights Commission has drawn a direct line between staffing shortages and the failure to meet legal obligations under the Education Act and the Ontario Human Rights Code. Students with disabilities are entitled to accommodation; in practice, boards that cannot hire enough special education staff are not providing it consistently.
And then there are EAs. $20 to $26 per hour, no summers. Amazon warehouses pay the same, without the emotional toll of working with high-needs children.
Cheap Child Care Is Poaching Kindergarten Staff
Ontario’s $10-a-day child care expansion has created a parallel staffing crisis that compounds the teacher shortage. Registered Early Childhood Educators (RECEs), who work alongside teachers in full-day kindergarten classrooms, are leaving school boards for child care centres that now offer competitive pay under the federal-provincial child care agreement. Before the child care deal, school board RECE positions were among the better-paying jobs in the sector. That advantage has eroded, and kindergarten classrooms are now operating without their full complement of staff. Good policy in one ministry creating a staffing crisis in another (a problem nobody in government wants to own).
Why Tradespeople Won’t Teach
Ontario has spent years promoting skilled trades as a career path. The pipeline for teaching those trades hasn’t kept up. A skilled electrician pulling $90,000 with overtime is not going to quit, spend two years in teachers’ college, and accept a starting salary that might be lower. Why would they? The Ontario Teachers’ Federation says the answer is making teaching attractive to tradespeople, not watering down qualifications.
International Recruitment
To address the shortfall, Ontario has turned increasingly to internationally educated teachers (IETs). The OCT certified approximately 2,200 internationally trained teachers in 2024, up from about 1,600 in 2021. Many come from the United Kingdom, Australia, India, and the Philippines.
Getting certified is its own ordeal. The OCT’s credential assessment takes six months to a year, and many applicants must complete additional coursework in Ontario curriculum and special education before receiving full certification. Qualified teachers sitting idle while classrooms go unstaffed. Language testing adds another barrier: teachers with decades of classroom experience in non-English-speaking countries still need to pass standardized English proficiency tests before the OCT will even process their applications.
Queen’s Park’s Response So Far
$55.8 million for 2,600 new teacher education spaces by 2027, focused on underserved regions and accelerated programs. Education Minister Paul Calandra has floated shortening teachers’ college, though no formal announcement has followed.
Here’s the catch. Ministry of Education research found longer practicums correlate with higher retention. Ontario’s 80-day practicum is already among Canada’s shortest; other provinces require 14 to 24 weeks. Shorten the program and you fill classrooms faster. Lengthen it and more of those teachers actually stick around.
The government hasn’t decided which problem it cares about more.
When the Supply Pool Runs Dry
Behind the daily shortage numbers sits a deeper problem: supply (substitute) teacher availability. When a teacher is absent, boards draw from a pool of occasional teachers. In many regions, that pool is exhausted before the morning bell, leaving administrators to combine classes, pull education assistants, or send students to the library.
It’s a vicious cycle. Regular teachers who know their absences create chaos are less likely to take sick days, leading to burnout, leading to longer absences, leading to the supply pool draining further. The system eats itself.
Burning Out the Teachers Who Stay
68% of respondents in a 2024 ETFO survey described their workload as unmanageable, up from 54% in 2019. The Ontario Secondary School Teachers’ Federation reported similar numbers among its membership. Teachers filling in the gaps report rising stress, anxiety, and compassion fatigue.
Prep periods vanish first. Teachers covering for absent colleagues lose their preparation periods, the time designated for marking, lesson planning, and parent communication. When that time disappears repeatedly, the work doesn’t vanish. It moves to evenings and weekends. Principals who can’t find supply teachers are stepping into classrooms themselves, which means the administrative work of running a school piles up too.
Younger teachers, who entered the profession during or after the pandemic, report particular difficulty. They arrived in schools that were already short-staffed, with mentorship programs stretched thin and experienced colleagues too overburdened to offer informal guidance. These are the teachers most likely to quit. And the ones the system can least afford to lose.
Cards and Seats Won’t Fix This
The $750 classroom supplies card announced in March 2026 addresses one frustration. The 2,600 new education spaces address another.
Neither touches the systemic drivers: compensation, workload, and working conditions relative to alternative careers. A supply card is nice. It is not a workforce strategy.
