On October 14, 2026, the Montreal Metro celebrated its 60th anniversary. The Société de transport de Montréal (STM) warned that roughly half of its infrastructure is classified as poor or very poor, and that postponing needed investments could lead to more frequent breakdowns and station closures.
The subway system, which opened in 1966 and is operated by the STM, now faces the challenge of aging assets as it reaches this milestone.
