This service shows the proportion of average total income of households which is spent on shelter costs by census subdivision. The data is from the Census Profile, Statistics Canada Catalogue no. 98-316-X2016001.Shelter-cost-to-income ratio is calculated for private households living in owned or rented dwellings who reported a total household income greater than zero.Private households living in band housing, located on an agricultural operation that is operated by a member of the household, and households who reported a zero or negative total household income are excluded.The relatively high shelter-costs-to-household income ratios for some households may have resulted from the difference in the reference period for shelter costs and household total income data. The reference period for shelter cost data is 2016, while household total income is reported for the year 2015. As well, for some households, the 2015 household total income may represent income for only part of a year.For additional information refer to the 2016 Census Dictionary for 'Total income' and 'Shelter cost'.To have a cartographic representation of the ecumene with this socio-economic indicator, it is recommended to add as the first layer, the “NRCan - 2016 population ecumene by census subdivision” web service, accessible in the data resources section below.

Mean 2014 to 2023 demersal fish total biomass in the Estuary and Gulf of St.Lawrence obtained by summing the fish biomass (kg) for all species for a tow and then averaging tows in each grid cell 10 km x 10 km. Input data are from the annual August (north) and September (south) multidisciplinary surveys. A distinct layer by survey is presented because the total biomasses are not comparable from one survey to the other (different fishing gears for each one).PurposeSince 1990, the Department of Fisheries and Oceans has been conducting an annual multidisciplinary survey in the Estuary and northern Gulf of St. Lawrence using a standardized protocol. In the southern Gulf of St. Lawrence, these bottom trawl surveys has been carrying out each September since 1971. These missions are an important source of information about the status of the marine ressources.The objectives of the surveys are multiple: to estimate the abundance and biomass of groundfish and invertebrates, to identify the spatial distribution and biological characteristics of these species, to monitor the biodiversity of the Estuary and Gulf and finally, to describe the environmental conditions observed in the area at the moment of the sampling.The southern Gulf surveys are realized using the following standardized protocol:Hurlbut,T. and D.Clay (eds) 1990.

The contaminants in fish database is a compilation of contaminant data analysed from fish tissue at the Fresh Water Institute from 1970 to 2005. Data include lab number, region, analysis, organs, species, lake, form (whole fish, headon dressed, headless dressed), weight, and length and contaminant concentrations. Total mercury was the predominant contaminant measured. Results were expressed as ppm or ppb based on the parameter analyzed. Concentrations are expressed based on wet weight.

The air monitoring stations measure up to 6 common pollutants like: * ground-level ozone * fine particulate matter * nitrogen dioxide * carbon monoxide * sulphur dioxide * total reduced sulphur compounds The Ministry of the Environment, Conservation and Parks continually monitors air quality across Ontario. We use this information to: * inform the public about outdoor ambient air quality through the Air Quality Index (AQI) and Smog Advisory program * assess Ontario's air quality and evaluate long-term trends * identify areas where pollutant levels are exceeded * identify the origins of pollutants * develop air policy * provide quantitative measurements to reduce specific pollution sources * determine the significance of pollutants from long-range transports and their effects * provide air quality researchers with data to link environmental and human health effects to air quality

This service shows the median total income of households in 2015 for Canada by 2016 census subdivision. The data is from the Census Profile, Statistics Canada Catalogue no. 98-316-X2016001.Total income refers to the sum of certain incomes (in cash and, in some circumstances, in kind) of the statistical unit during a specified reference period. The median income of a specified group is the amount that divides the income distribution of that group into two halves. For additional information refer to 'Total income' in the 2016 Census Dictionary.For additional information refer to 'Total income' in the 2016 Census Dictionary.To have a cartographic representation of the ecumene with this socio-economic indicator, it is recommended to add as the first layer, the “NRCan - 2016 population ecumene by census subdivision” web service, accessible in the data resources section below.

The National Ecological Framework for Canada's "Total Land and Water Area by Ecoregion” dataset provides land and water area values for ecoregion framework polygons, in hectares. It includes attributes for a polygon’s total area, land-only area and large water body area.
