Forum to address climate change and effects on water management in Outaouais

Tashi Farmilo

As climate-driven weather events escalate across the Ottawa River watershed, more than 150 municipalities, including regional county municipalities and Indigenous communities, are being called to gather for the TCO 2026 Municipal Forum, Rethinking Water. Organized by the Ottawa River Consultation Table (TCO) in partnership with five watershed organizations, the forum will take place in Aylmer on June 4 at the Château Cartier.

The event is aimed at elected officials, municipal administrators, emergency personnel and public works staff, all of whom are facing growing pressure to adapt local infrastructure and services to more volatile weather conditions. The goal is to equip communities across the Ottawa River watershed, also known by its Algonquin name Kichi Sibi, with the tools and knowledge they need to respond effectively to climate change impacts, particularly related to water.

In recent years, the Outaouais has seen record-breaking floods and increasingly erratic precipitation. In Aylmer and nearby parts of Gatineau, spring flooding has inundated roads and homes. In 2017 and 2019, high water levels in the Ottawa River led to emergency declarations and widespread evacuations. Levels right now are around 2023 levels, with streets flooded and residents evacuated. Local experts warn that freeze-thaw cycles are becoming harder to predict, and intense rainfall events are more likely to overwhelm existing stormwater systems.

The forum will offer concrete guidance on managing these risks. Topics will include green infrastructure like rain gardens and permeable pavement, natural floodplain restoration, municipal vulnerability assessments, and coordinated emergency response planning. Attendees will also hear from neighbouring municipalities and Indigenous communities that are already implementing successful mitigation strategies.

Beyond technical solutions, the forum emphasizes the importance of collaboration. Organizers hope to strengthen relationships between municipalities, regional watershed organizations, and Indigenous governments to support integrated water governance across the basin. Because water knows no boundaries, the forum advocates for a shared, regional approach to managing risk.

The one-day event at the Château Cartier will feature presentations, panel discussions, and interactive workshops. It is open to all municipalities and communities within the watershed territory.
