Canada is one of the most water-rich countries in the world, however not all Canadians have access to reliable potable drinking water (Galway 1). First Nations communities are disproportionately impacted by unsafe drinking water; they are 90 times more likely to be without safe and reliable drinking water (Thomson et. al. 378; Galway 2). Additionally, the number of water-borne illnesses and infections in First Nations communities is 26 times higher than the national average (Galway 2). This disturbing inequity cannot be viewed in isolation. This problem is compounded by underlying social, political, and economic marginalization of Indigenous peoples (Galway 2), and exists partially as a result of “the legacy of colonialism, forced relocation, residential schools and systemic racism in Canada” (David Suzuki Foundation Report 8). Safe and reliable drinking water for all First Nations communities is a public health and safety issue, as well as an environmental justice issue, across Canada (Galway 8).
The province of Ontario illustrates this problem particularly well; as of November 2016, Ontario had the highest number of Drinking Water Advisories (DWAs) in First Nations reserves in Canada (David Suzuki Foundation Report 7). DWAs are issued when a community’s water may be unsafe or is known not to be safe. The three types of drinking water advisories, defined by Health Canada, are: Boil Water Advisory, Do Not Consume, and Do Not Use (Galway 3; David Suzuki Foundation Report 10). Currently, there are no Do Not Use orders in Ontario, therefore we have excluded this category from our maps. The majority of DWAs are Boil Water Advisories (Thomson et. al. 383), these are issued when “the microbiological quality of drinking water is suspected or confirmed to be compromised, meaning disease-causing micro-organisms, such as bacteria, viruses or parasites, could be in the drinking water” (Galway 3). Do Not Consume orders represent a smaller proportion of DWAs and are issued when “contaminants are present that cannot be removed through boiling” (Galway 3). Human Rights Watch states that contaminants in drinking water on First Nations reserves include coliform, Escherichia coli (E. coli), cancer-causing Trihalomethanes, and uranium (9).
