Project tracker
Projected lift date: TBD
Deer Lake First Nation in Ontario is home to 1,124 people on reserve.
There is 1 long-term drinking water advisory in Deer Lake:
- a boil water advisory was set on the Deer Lake Public Water System in October 2019 and became long-term in October 2020
The long-term drinking water advisory affects 225 homes and 5 community buildings.
Deer Lake First Nation has completed interim repairs to its water treatment system and is advancing a feasibility study to examine the community's long-term needs and options. Funding support is being provided by Indigenous Services Canada (ISC).
Although testing shows the treated water meets regulatory requirements, consistent operations and monitoring are required before the advisory can be lifted.
Deer Lake receives operational support from the ISC-funded Centralized Water and Wastewater Hub, delivered by the Keewaytinook Okimakanak Tribal Council. Through the hub, a certified water operator provides oversight of water and wastewater operations.
The community, with support from ISC, lifted another long-term drinking water advisory affecting its nursing station in 2018.
