TORONTO (Thomson Reuters Foundation) - When an oily sheen was discovered on the surface of the local water reservoir in October, Canada’s Neskantaga First Nation was forced to close off the pipes and move. Isolated in remote northern Ontario, accessible only by plane or on winter roads, nearly all 300 residents evacuated to Thunder Bay, more than 400 kilometers away, breaking the protective bubble of isolation they had tried to build during COVID-19. Weeks later, they are living in hotels, waiting for clean-up repairs and tests to confirm that the water is safe enough to go home. The evacuation is just the latest water crisis in Neskantaga, where even in normal times the water is considered unsafe. Despite many attempted repairs and upgrades, for 25 years the community has been under a boil-water advisory - a public health directive to drink boiled or bottled water issued when the water is considered a potential health risk. Neskantaga has the longest-running advisory in Canada, but it is just one of more than 40 indigenous communities without access to a drinkable water supply. “All we want is a clean glass of water coming out of our taps,” Neskantaga chief Chris Moonias told the Thomson Reuters Foundation. “Sometimes you don’t even feel like you’re being treated as a basic human being.” The community’s water system was built in 1993 and has been plagued with issues ever since, including problems with the treatment plant, chemical contamination and a faulty distribution system. Indigenous people in dozens of communities across Canada live with water supplies that are unclean or degraded, according to a report by Human Rights Watch in 2016. Some have poor treatment systems and others have water that is contaminated naturally, by faulty wastewater management or from despoiled sources, it said.The federal government of Prime Minister Justin Trudeau lifted 88 boil-water advisories from November 2015 to February 2020 through efforts like building or upgrading water treatment plants. It had promised to lift all remaining advisories by March 2021 but has since back-tracked, citing COVID-19 disruption. “It is too early to determine the full impact of COVID-19 on water infrastructure timelines, but we remain aggressively committed on the Spring 2021 goal,” said the office of Marc Miller, Minister of Indigenous Services Canada, in an email to the Thomson Reuters Foundation. The Neskantaga First Nation, who live along Attawapiskat Lake in northern Ontario, was relocated to its current location starting in the 1980s, with an offer of better services including water, according to Human Rights Watch. An CAD$8.8 million federal investment in 2017 was supposed to upgrade Neskantaga’s water treatment plant, but Moonias said costs have almost doubled to more than CAD$16 million due to various ongoing issues.
