Parents defied the Ford government’s livestream ban at a school board committee meeting last night. They recorded & broadcast the TDSB’s special education meeting despite the education minister ordering them to stop. “Why on earth would there be any interest in suppressing this?”
✊🏽 Solidarity with OPSEU351 on Strike! ✊🏽
We stand firmly with the members of OPSEU351 who are currently on strike, fighting for fair pay, job security, and the respect they deserve.
Their struggle is our struggle — and we’re proud to contribute to their hardship fund.
Hands off our Schools!
ETFO President David Mastin joins presidents of OECTA, OSSTF and the OBSCU and MPP Pasma at the ONDP Convention to demand the Ford Government withdraw Bill 33 and stand up for public schools.

We're excited to announce ETFO President David Mastin as a Speaker at the Niagara Convention!
David began his teaching career in 1995 with the Durham Board of Education (now Durham District School Board) after graduating from the University of Toronto.
At the ETFO Durham Teacher Local, he served as local Treasurer, Secretary, Chief Negotiator, Political Action Chair, Second Vice-President and First Vice-President before being elected local President in 2015.
David was first elected to ETFO’s Provincial Executive in 2013, he was elected Vice-President in 2019, First Vice-President in 2021 and President in 2025.
With public education, equity, and workers’ rights under threat, David knows our greatest strength lies in unity, action, solidarity, and hope.

BREAKING: Ontario college workers are fighting back to save the public college system and defend a future of learning and supports for students. Join the line, and together we can help save public education from a privatized system where Ford's friends benefit! #onpoli
More than 10,000 full-time college support staff are ON STRIKE as of 12:01 a.m. This is not just a fight for a contract – it’s about the future of student support. We’re fighting because we know our students need us.

🚨 WATCH THIS: Today's Fall Economic Statement proves it. With Doug Ford, you're not getting what you paid for.
This is a mind-boggling weird statement…

Ontarians deserve better than a government under RCMP criminal investigation. I'm calling on Doug Ford to come clean.

I took a screenshot of this bc CPC stuff gets erased when they realize how asinine they look.
But can someone pls explain WTAF “MTG of the North” is trying to claim here?!
Parents can’t make ends meet so they are trafficking their children?!
This is completely unhinged!

Last week, I was on the road to hear more from Ontarians about what they need out of the 2023-2024 budget – out Thursday. 🧵 #onpoli

Crowded classes are preventing our kids from getting the help they need to catch up from the pandemic. It's time for a cap on class sizes.
Proudly supporting Drag Story Time with @bettyybaker! Our library includes everyone! instagram.com/p/CpF0N12ucmE/…
