This dataset includes five depth-attenuated relative wave exposure index layers in raster format. Relative Exposure Index (REI) values are calculated based on effective fetch (derived from fetch values) combined with modelled wind data. The output REI layers are attenuated by depth, resulting in...

The 2008-2022 Total Diet Study Food Consumption Tables show the daily consumption of each Total Diet Study (TDS) food composite for various age-sex groups. The source for these consumption data is the 2015 Canadian Community Health Survey-Nutrition Component (2015 CCHS-Nutrition). When paired...

Arsenic is naturally occurring in the environment, and very low levels are present in various foods. Elevated arsenic exposure from drinking water has been associated with a variety of serious adverse health effects, with potential effects noted in vulnerable populations such as infants and...

A cross-over study was conducted among 42 healthy adults during the summer of 2010 in Ottawa, Canada. Participants cycled for 1 hour along high and low traffic routes and ultrafine particles (UFPs) 0.1um in aerodynamic diameter, particulate matter (PM2.5) 2.5 µm in aerodynamic diameter, and black...

This evergreen document will be updated as COVID-19 vaccines are authorized and become available for use in Canada, and as evidence on these vaccines and COVID-19 evolves. This table summarizes the latest changes to this current version. Please refer to the Table of updates for a full list of...

This guidance supports high quality investigations that will contribute to public health’s collective understanding of COVID-19 transmission in all types of school settings and the utility of mitigation measures implemented. A systematic approach to outbreak response, including an investigation...

COVID Alert is Canada's free exposure notification application. COVID Alert helps us break the cycle of infection. The application can let people know of possible exposures before any symptoms appear.

Freshwater mussels contribute important ecological functions to aquatic systems. The water filtered by mussel assemblages can improve water quality, and the mixing of sediments by burrowing mussels can improve oxygen content and release nutrients. However, nearly 70 percent of North American...
