Why Canadian TAs and RAs Have Been on Strike: Inside the Stipend Campaigns
By Muntasir • Published Aug 01, 2026 • Updated Sep 20, 2026 • Graduate & Professional School, Canadian Universities & Colleges
Canadian teaching and research assistants have walked picket lines repeatedly since the 2000s, most often over stipends that lag behind rent and tuition, and York University's CUPE 3903 holds the longest strike record in the country. The core demand across campuses is the same: a guaranteed minimum funding floor that keeps pace with the cost of living in the city where the university sits.
📩 York's CUPE 3903 struck in 2000-01, 2008-09 (ended by back-to-work legislation after roughly 85 days), 2015, 2018, and again in 2024 (about 8 weeks, Feb 26-Apr 19), before ratifying a new 3-year contract.
💵 The recurring demand is a minimum funding floor, not just a per-hour wage increase.
⏱️ A strike can delay grading, tutorials, labs and sometimes term-end dates.
CUPE 3903 opened a new round of bargaining across its TA, RA and contract faculty units in 2026.
The pattern behind the picket lines
Canadian graduate worker strikes follow a repeating shape. A local union, usually a CUPE or PSAC affiliate representing teaching assistants, research assistants and sometimes contract faculty, reaches the end of its collective agreement and opens bargaining. The university offers a wage increase tied to standard inflation adjustments. The union argues the increase does not close the gap between what a stipend covers and what rent, tuition and basic costs run in that city, and asks for a guaranteed minimum funding floor instead of a per-hour rate alone. When talks stall, the union takes a strike vote, and if it passes, members walk out.
York's CUPE 3903: the longest running fight
CUPE 3903, representing teaching assistants, graduate assistants and contract faculty at York University in Toronto, has struck more than once and holds one of the longest post-secondary strike records in Canadian history: a roughly 85-day strike in the 2008-09 academic year that ended after the Ontario government passed back-to-work legislation. The local also struck in 2000-01, for about four weeks in 2015, and for about 20 weeks (143 days) in 2018 -- the longest post-secondary strike in Canadian history at the time -- ended by Ontario back-to-work legislation. CUPE 3903 also struck again more recently, from Feb 26 to Apr 19, 2024 (about 8 weeks), before members ratified a new 3-year agreement. Each round centred on the same core issue: whether the guaranteed minimum funding for a graduate student doing TA or RA work in Toronto, one of the most expensive Canadian cities to live in, keeps pace with actual costs.
As of the 2025-26 bargaining round, CUPE 3903 confirms on its own site that bargaining for its Unit 1, 2 and 3 members has started again, continuing the same pattern of returning to the table each time an agreement expires.
What unions are asking for now
Across Canadian campuses, the common ask in recent rounds is a minimum funding floor: a guaranteed total annual amount a funded graduate student receives regardless of how few TA or RA hours they are assigned in a given term, rather than only an hourly wage that leaves total income unpredictable term to term. Unions frame this around local rent, arguing that stipend increases tied only to general inflation measures do not reflect how fast rent has risen in cities like Toronto, Vancouver and Montreal specifically.
Beyond York: a national pattern, not one campus
York is the most documented case because of its strike history, but graduate worker unions at other Canadian universities have gone through their own contentious bargaining rounds in the same period, often citing the same rent-versus-stipend gap in cities like Vancouver and Montreal. The specific timeline, demands and settlement terms differ local by local, so check the specific CUPE or PSAC local at your own university directly for what actually happened there and what the current agreement says, rather than assuming one campus's outcome applies everywhere.
What a strike means for you as a student
If your TAs or RAs are on strike, expect delayed grading, cancelled tutorials or labs, and sometimes a delayed exam or term-end schedule while the university and union negotiate replacement arrangements. Universities typically post strike updates and academic contingency plans on a dedicated webpage during a labour dispute. Check your university's official strike or labour relations page directly for how your specific courses and deadlines are affected, since contingency rules differ by faculty and even by course.
Some universities also offer an incomplete grade extension or a coursework completion window once TAs return, rather than penalizing you for a disruption outside your control. Ask your registrar's office directly what applies to your specific courses during an active labour dispute.
