WATER TODAY Advisory Maps
WATERTODAY updates and posts Canadian water advisories throughout the day, every day. Establishing drinking water quality criteria and publishing water advisories is a provincial responsibility in Canada.
WATERTODAY national maps offer site visitors an overview of water issues across Canada, including: Boil Water Advisories (BWA - yellow dots) Do Not Consume (DNC - red dots), Water Shortage (WS - purple dots) and cyanobacteria contamination or Blue-Green Algae (cyan dots) advisories.
Our provincial maps provide additional details such as advisory locations and causes.
In order to post as many active DWAs (Drinking Water Advisories) as possible, we utilize a number of sources including governmental lists (Provincial and Municipal), as well as Federal lists of First Nation advisories, in addition to subscribing to the media lists of municipalities and health units across the country and to a number of media outlets. In addition, we take a proactive approach and seek out new DWAs through online searches (Google, etc).
Despite our efforts to make our list of advisories as comprehensive as possible, it may happen that one or more issued DWAs will be missed, or that a previously issued DWA will have been rescinded yet still appear on our map as active. Should you be aware of either please inform us via email.
For the sake of map clarity, when there are more than one advisory in a community, WATER TODAY groups them under one name, i.e. TownName (5). This avoids overcrowding the maps with pinpoints, making them difficult to read. This is especially the case in British Columbia, where one community may have many individual water systems.
