Construction/renovation with excavation: Molson between William-Tremblay and Mont-Royal

A 24-hour construction project involving excavation will shut down a stretch of Molson Street between William-Tremblay and Mont-Royal from April 15 to 16, 2026, according to the City of Montreal. The Société du Patrimoine Angus Résidentiel has received permits for the work, which begins at 8 PM on Tuesday and wraps up by 8 PM Wednesday. The timing suggests this isn't your typical pothole patch-up. Construction projects that require excavation permits and run around the clock usually involve serious infrastructure work — think water mains, gas lines, or major utility installations. The Société du Patrimoine Angus is the development arm behind the massive Technopôle Angus project, which has been transforming the former Canadian Pacific Railway shops in Rosemont into a mixed-use community for over two decades. For West Island residents, this might seem like just another downtown construction headache, but it's worth noting if you're planning any trips to the Plateau or have family in the area. Molson Street runs parallel to Saint-Laurent Boulevard and connects several major east-west arteries, making it a key route for anyone navigating Montreal's central neighborhoods. The affected stretch sits in the heart of the Plateau-Mont-Royal borough, close enough to popular destinations like Mount Royal Park and the Main that detours could ripple through your weekend plans. The one-day timeline is actually refreshing in a city where orange cones have become permanent landscape features. Most major excavation projects drag on for weeks or months, turning neighborhoods into obstacle courses that would challenge even the most patient Montrealer. This surgical strike approach suggests the developers have their logistics dialed in — or at least that's what we're all hoping. The permit was issued recently, giving local residents and businesses minimal time to adjust their routines. While the city's construction notification system has improved over the years, 24-hour projects still tend to catch people off guard, especially when they involve streets that serve as shortcuts between major thoroughfares. Given that this is scheduled for 2026, there's plenty of time for plans to change, permits to be modified, or timelines to shift. But for now, mark your calendars if you're the type who plans that far ahead — or just file this away as another reminder that in Montreal, the only constant is construction, and the only surprise is when it actually finishes on schedule.
