There is about 6 hundred First Nation communities in Canada; about 73% of First Nation's water in Canada is at high risk of contamination.
The First Nations water crisis began as far back as 1995.
To install a community well to provide clean drinking water in these communities would be around $10 000, though the government has dismissed this solution in coloured communities.
The water supply for Brooklin comes from Lake Ontario.
Brooklin used to have its own water supply plant, but it was demolished in 2009.
Water for Brooklin is treated at the Lake Ontario Water Treatment Plant.
The Lake Ontario Water Treatment Plant is located in the Town of Oswego.

Climate change can change water levels and temperature; pollution from residential and industrial areas can reduce water quality.
