About Greve STM: Your Transit Strike Information Resource
Our Mission and Purpose
Greve STM was created to address a critical information gap that Montreal commuters face during transit strikes. When the STM experiences labor disruptions, finding reliable, up-to-date information becomes challenging as official sources can be overwhelmed and information becomes scattered across multiple platforms. Our mission is to centralize accurate strike information, provide context about labor disputes, and offer practical guidance for commuters navigating service disruptions.
We recognize that transit strikes affect different communities unequally. While downtown professionals may have remote work options or alternative transportation, service workers, healthcare employees, students, and others with inflexible schedules face significant challenges. Our goal is to democratize access to strike information, ensuring that all commuters, regardless of language, technical literacy, or economic resources, can access the information they need to plan their travel during disruptions.
The platform emerged from firsthand experience with the confusion and frustration that strikes create. During the 2022 strike actions, we observed how difficult it was to find clear answers to basic questions: Which routes are operating? When will service resume? What alternatives exist? By aggregating information from official STM sources, union communications, news coverage, and historical strike data, we created a resource that answers these questions in one accessible location.
Our commitment extends beyond simply reporting strike dates. We provide context about why strikes occur, what workers are demanding, and how negotiations progress. Understanding the human dimension of labor disputes—the safety concerns, compensation issues, and working conditions that drive workers to strike—helps commuters see beyond inconvenience to the legitimate workplace issues at stake. This balanced perspective supports informed public discourse about transit funding, labor relations, and the value of public services.
How We Gather and Verify Strike Information
Accuracy is paramount when commuters depend on our information for critical travel decisions. We employ a multi-source verification approach that cross-references official STM announcements with union communications, news reports, and direct observation. Our information gathering process begins with monitoring official STM channels, including their website, social media accounts, and press releases. We track announcements from the four primary unions representing STM workers: the Syndicat du transport de Montréal (CSN), maintenance unions, administrative workers, and technical staff associations.
We maintain relationships with local journalists covering labor and transportation issues, providing early awareness of developing strike situations. News outlets like CBC Montreal, Montreal Gazette, La Presse, and Journal de Montréal employ reporters who attend negotiation sessions and have direct access to both management and union representatives. Their reporting provides valuable context that raw announcements lack, helping us understand not just what is happening but why and what might happen next.
Historical strike data forms another crucial verification layer. By analyzing patterns from past strikes—typical duration, service levels during different types of actions, settlement terms, and seasonal timing—we can provide informed projections about current situations. We maintain a database of STM strikes dating back to 1974, including details about causes, duration, service impacts, and resolutions. This historical perspective helps distinguish routine negotiation tactics from serious labor disputes likely to result in extended disruptions.
We update our information multiple times daily during active strike periods, with verification protocols requiring confirmation from at least two independent sources before publishing service changes. When official information is unclear or contradictory, we clearly indicate uncertainty rather than speculating. Our FAQ section addresses common questions with detailed, evidence-based answers, while our main page provides current strike status and schedule information. We also link to authoritative external sources, encouraging users to verify critical information through official STM channels before making important travel decisions.

Supporting Montreal Commuters Through Transit Challenges
Beyond providing strike information, Greve STM serves as a comprehensive resource for understanding Montreal's transit system and the broader challenges facing urban public transportation. Our content explores alternative transportation options, from the REM light rail system to bike-sharing networks, helping commuters develop backup plans that work for their specific needs and circumstances. We recognize that a downtown office worker has different alternatives than a retail employee in the suburbs, and we address this diversity in our guidance.
The economic impact of transit strikes extends far beyond individual inconvenience. Studies estimate that major STM strikes cost the Montreal regional economy $20-30 million per day in lost productivity, increased transportation costs, and business disruptions. Small businesses in particular suffer when customer access becomes difficult and employees struggle to reach work. We document these broader impacts to support informed public discussion about transit funding, the importance of stable labor relations, and the true cost of underinvesting in public transportation infrastructure.
Environmental considerations also factor into our coverage. When transit strikes force commuters into private vehicles, Montreal's transportation-related carbon emissions increase by an estimated 15-20% for the strike duration. A single day of complete STM shutdown generates approximately 2,500 additional tons of CO2 emissions compared to normal operations. These environmental costs underscore why efficient public transit matters beyond convenience—it's essential infrastructure for meeting climate goals and maintaining urban air quality.
Looking forward, we're committed to expanding our coverage as Montreal's transit landscape evolves. The REM expansion, STM fleet modernization, and changing commuter patterns post-pandemic all affect how strikes impact the city. We'll continue monitoring these developments, updating our resources, and providing the accurate, timely information that Montreal commuters need to maintain mobility during labor disruptions. Our FAQ page offers detailed answers to specific questions, while our home page provides current strike status and practical guidance for immediate travel planning.
