Around 7 a.m. on Saturday, September 19, 2026, the Sûreté du Québec announced the arrest of two individuals who had climbed the Jacques‑Cartier Bridge. The police operation also confirmed that two other participants remain at large, and traffic on the bridge was restored shortly after the arrests.
The incident involved a total of four people who were seen walking along the steel trusses of the bridge that connects the Island of Montreal to Longueuil. Witnesses reported the unusual activity to authorities, prompting an immediate police response.
Officers from the Sûreté du Québec arrived on the scene, secured the area and identified the four individuals. Two of them were taken into custody without incident. The remaining two suspects fled the bridge before they could be apprehended, and a search effort is ongoing to locate them.
The Jacques‑Cartier Bridge is a major commuter artery for thousands of drivers each day. Its temporary closure caused a brief disruption to the flow of traffic between Montreal and Longueuil. After the two arrests were completed, police lifted the closure and normal traffic resumed, allowing commuters to continue their journeys.
Authorities have not released the identities of the arrested persons or the two individuals still at large. The Sûreté du Québec emphasized that the investigation remains active and that any further information could assist in locating the remaining suspects. The police department reiterated its commitment to maintaining safety on critical infrastructure such as the Jacques‑Cartier Bridge.
The incident underscores the rapid response capabilities of Quebec’s law‑enforcement agencies when unusual activity is reported on key transportation routes. While the bridge has reopened, the search for the two remaining individuals continues, and officials have asked the public to report any relevant observations.
