As of May 2026, data from Indigenous Services Canada (ISC) indicates that 40 long-term drinking water advisories (LTDWAs) remain in effect across 37 First Nations communities. While the headline number remains a point of political debate, the engineering reality on the ground is one of high-intensity construction. Of the remaining 40 advisories, over 80 per cent have active infrastructure projects currently in the design or construction phases.
Under Construction: 5 Communities to Watch in 2026
The path to lifting an advisory is rarely linear, often involving multi-year construction cycles. Here is a status update on five key projects currently in the construction phase:
1. Neskantaga First Nation, Ontario
Advisory Since: February 1995
Project Scope: Comprehensive upgrade to the existing water treatment plant and distribution system to address long-standing structural integrity issues.
Current Status: Final mechanical commissioning. Following a series of setbacks in 2024, the project is now entering the 24-hour testing phase.
Estimated Completion: Late Summer 2026
2. North Spirit Lake First Nation, Ontario
Advisory Since: May 2001
Project Scope: Construction of a brand-new water treatment plant and intake system to replace the decommissioned facility.
Current Status: Structural build is 90% complete. Electrical and controls installation is currently underway by contractors.
Estimated Completion: December 2026
3. Oneida Nation of the Thames, Ontario
Advisory Since: September 2019
Project Scope: Major pipeline connection project to link the community to the regional Lake Huron water supply system.
Current Status: Trenching and pipe-laying are active. Over 15km of the connection is now in the ground.
Estimated Completion: Autumn 2026
4. Tataskweyak Cree Nation, Manitoba
Advisory Since: June 2017
Project Scope: Expansion of treatment capacity and implementation of advanced filtration to deal with high turbidity and organic loads.
Current Status: Construction of the filtration annex is complete; membrane installation began in April 2026.
Estimated Completion: Spring 2027
5. Shamattawa First Nation, Manitoba
Advisory Since: December 2018
Project Scope: System-wide emergency repairs and the construction of a new reservoir to ensure consistent pressure and fire safety.
Current Status: Foundation for the reservoir has been poured. Logistical challenges due to winter road conditions have pushed the final phase to this summer.
Estimated Completion: November 2026
Tracking the 2026 Pipeline
While these five projects represent the “heavy lifting” currently in the construction phase, ISC tracking indicates that an additional 12 communities are in the final feasibility or design stages. For these nations, the focus remains on securing procurement and identifying
qualified contractors—a task made increasingly difficult by the nationwide shortage of specialized civil and water engineers.
