In 1991, the National Task Force on Health Information cited a number of issues and problems with the health information system. To respond to these issues, the Canadian Institute for Health Information (CIHI), Statistics Canada and Health Canada joined forces to create a Health Information Roadmap. From this mandate, the Canadian Community Health Survey (CCHS) was conceived.The CCHS is a cross-sectional survey that collects information related to health status, health care utilization and health determinants for the Canadian population. The survey is offered in both official languages. It relies upon a large sample of respondents and is designed to provide reliable estimates at the health region level every 2 years.The primary use of the CCHS data is for health surveillance and population health research. The data presented here is by age group and sex, for Canada, provinces, territories and health regions (2017 boundaries).

As the COVID-19 pandemic spreads, researchers and health professionals have noted large differences in the impact that the infection has on individuals. Whereas some remain asymptomatic and unaware of their infection or experience only mild symptoms, others require hospitalization, ventilation, and may even die. As research evidence accumulates, both nationally and internationally, it appears that certain health characteristics, such as obesity or the presence of chronic conditions, increase the risk of severe outcomes among those who are infected with the novel coronavirus.To better understand which segments of the Canadian population may be vulnerable to severe health outcomes related to COVID-19, Statistics Canada and the Public Health Agency of Canada have worked collaboratively to build an index of underlying health conditions in the adult household population. Using information from the 2017/2018 Canadian Community Health Survey, new data tables released today estimate the proportion of the adult household population who may be at greater risk of severe health outcomes related to COVID-19 due to the presence of underlying health conditions.

This dataset provides the results obtained by Health Canada’s Canadian Radiological Monitoring Network (CRMN) for the gross alpha and beta activity concentrations in drinking water, given in units of becquerels per liter (Bq/L). More information about the CRMN network can be found on the Health Canada website (see link below). Although water quality is a matter of provincial jurisdiction, the CRMN, in collaboration with the city of Ottawa, has been conducting a targeted program to monitor the radiological content of drinking water from two water treatment plants in Ottawa, ON. The Guidelines for Canadian Drinking Water Quality recommend screening levels of 0.5 Bq/L and 1.0 Bq/L for gross alpha and gross beta activity, respectively. The screening levels are set to reflect the most restrictive Maximum Acceptable Concentrations (MACs) for specific radionuclides in drinking water. If the screening levels are not exceeded, compliance with the guidelines can be inferred. The screening levels set out in the Guidelines for Canadian Drinking Water Quality are calculated based on annual averages of radionuclides in drinking water. Short-term exposure to levels above those recommended by these guidelines does not indicate a health risk. The measured gross alpha and gross beta activity concentrations presented here are well below the screening levels set by the Guidelines for Canadian Drinking Water Quality, with only one exception to date. This occurred February 28, 2011, and was attributable to the flushing of lead pipes at the water treatment plant. It resulted in a spike of naturally occurring lead radionuclides that was dealt with immediately by the City of Ottawa. The map shows the approximate sampling location for each monitoring station. Stations are found within the associated location range.

The Air Quality Health Index (AQHI) is a scale designed to help quantify the quality of the air in a certain region on a scale from 1 to 10. When the amount of air pollution is very high, the number is reported as 10+. It also includes a category that describes the health risk associated with the index reading (e.g. Low, Moderate, High, or Very High Health Risk). The AQHI is calculated based on the relative risks of a combination of common air pollutants that are known to harm human health, including ground-level ozone, particulate matter, and nitrogen dioxide. The AQHI formulation captures only the short term or acute health risk (exposure of hour or days at a maximum). The formulation of the AQHI may change over time to reflect new understanding associated with air pollution health effects. The AQHI is calculated from data observed in real time, without being verified (quality control).

The Open Database of Healthcare Facilities (ODHF) is a collection of open data containing the names, types, and locations of health facilities across Canada. It is released under the Open Government License - Canada.The ODHF compiles open, publicly available, and directly-provided data on health facilities across Canada. Data sources include regional health authorities, provincial, territorial and municipal governments, and public health and professional healthcare bodies. This database aims to provide enhanced access to a harmonized listing of health facilities across Canada by making them available as open data. This database is a component of the Linkable Open Data Environment (LODE).

Ontario's Healthy Babies Healthy Children program helps infants and children up to age 6 and their families through: * risk screening and assessments * referrals to community programs and services * supports for new parents These shapefiles provide geospatial data for mapping the 34 Healthy Babies and Healthy Children delivery regions in Ontario. __Please note:__ The Healthy Babies Healthy Children program is delivered through Ontario’s public health units in partnership with hospitals and other community partners. The Healthy Babies Healthy Children boundaries align with Public Health Unit boundaries.

Community Areas are a standard analytical and service delivery geography for the city of Winnipeg and the Winnipeg Regional Health Authority.Community Areas are a standard analytical and service delivery geography for the city of Winnipeg and the Winnipeg Regional Health Authority.  The Community Areas geographic areas were developed by the Community Data Network (now more commonly referred to as the Winnipeg Community Data Consortium), with input from the WRHA, Manitoba Health, the City of Winnipeg, and other stakeholders. Community areas can be defined to either include or exclude the municipalities of East and West St. Paul. Because the Winnipeg RHA is defined to include East and West St. Paul, use of the geographies in a health services or health status context includes East and West St. Paul. Conversely, because the City of Winnipeg excludes East and West St. Paul, use of the geographies in a municipal administrative context excludes East and West St. Paul. This shapefile reflects the use of Community Areas in a health services or health status context, and includes East and West St. Paul.

RHA Districts are geographic areas that are used to define populations and catchment areas for the administration and delivery of health services. This file provides RHA district boundaries for cartographic and analytical purposes.Within Manitoba there are five Regional Health Authorities (or "RHAs") responsible for the delivery of health service in five specific areas of the province described as "health regions". (In practice, the terms "health region" and "RHA" are used interchangeably to describe these geographic areas.) In consultation with Manitoba Health, Healthy Living and Seniors, and with the Manitoba Centre for Health Policy, each of the RHAs has defined further subdivisions within each RHA . These sub-areas of each RHA generally correspond to areas of clustered population and/or service delivery. They are used to plan service delivery, and are also used to describe and analyze population health and health service use with more specificity than analysis at the RHA level could provide. Due to the size and the total population of Manitoba's RHAs, there are two levels of subdivided RHA geography which are used for analytical and planning purposes. The smallest subdivisions used for this purpose are RHA Districts. RHA Districts within an RHA are also grouped into larger sub-areas with the RHA called RHA Zones, within each RHA District within an RHA included in precisely one of these zone. This shapefile contains the boundaries of Manitoba's RHA districts.

The Ministry of Health Service Provider Locations (MOHSERLO) geospatial dataset contains the locations of health service providers in Ontario.

This dataset provides the results obtained by Health Canada’s Radiological Monitoring Network (CRMN) for tritium content in atmospheric water vapor sampled from monitoring stations in Ontario, Quebec and New Brunswick. More information about the CRMN network can be found on the Health Canada website (see link below). The results provided are for tritium activity concentration, expressed in units of becquerels per cubic meter (Bq/m3). Atmospheric water is sampled monthly for determination of tritium content. The majority of such monitoring activity occurs in close proximity to nuclear power plants. Until 1996, Health Canada monitored the areas near Darlington, Bruce and Pickering in Ontario, Gentilly in Quebec, and Point Lepreau in New Brunswick. In 1996, Health Canada’s monitoring of the Ontario stations was terminated to avoid redundancy, since a similar initiative was underway through the Ontario Ministry of Labour. Currently, the CRMN monitors six sites in the vicinity of Point Lepreau, four sites in the vicinity of Gentilly, and a single site in the Greater Toronto Area. The average tritium concentration for the CRMN stations is 0.22 Bq/m3 for the time period from 2004 to 2013. This is consistent with results reported for other monitoring stations in close proximity to Canadian nuclear power stations, and the levels are considered to be safe from a health perspective. Note that the tritium values are measured using liquid scintillator measurements. This requires removing the background contribution from the measurement. The uncertainty associated with each measurement, can lead to reported values of less than zero. The map shows the approximate sampling location for each monitoring station. Stations are found within the associated location range.
