The national wetland layer contains wetland data compiled from the best available data from each region, classified by wetland type. Wetlands are mapped as polygons in geographic layers, which are integrated into a master geodatabase at the national scale.Information from each contributing dataset was classified based on the Canadian Wetland Classification System, which contains five main wetland classes (Bog, Fen, Marsh, Swamp, and Shallow Water) that represent the types of wetlands encountered in Canada. An additional category, “partially classified” was used to preserve boundary information for wetlands that could not be classified into the main categories with existing information.

This collection of data summarizes the companies and facilities reporting under the Fuels Information Regulations, No. 1. This dataset includes total fuel volumes, sulphur contents and masses, and companies reporting production and/or importation of liquid fuels originating from crude oils, coal or bituminous sand. The information was provided to Environment and Climate Change Canada under the Canadian Environmental Protection Act, 1999.

The dataset contains the blended (gauge and satellite estimates) monthly mean precipitation rates (unit: mm/day) for Canada for the period from January 1979 to December 2007, at a half degree spatial resolution. Please refer to the paper below for the details of the blending algorithm and input gauge and satellite data. Reference: Lin, A. and X. L.

The Canadian Ice Service maintains a collection of Daily ice charts, Regional ice charts and Iceberg charts. These charts are available in GIF format and E00 (Regional Charts only).

This daily forecast describes the ice edge using latitude and longitude coordinates, the total ice concentration, the predominant ice stage of development and the concentration of the oldest ice type. Warnings are issued as appropriate. The forecasts are valid from the time of issue until the end of the following day (so for a period of 24 to 48 hours).

In the face of increasing economic opportunities in Canada's northern regions, the need to improve our state of preparedness for oil spill related emergencies in particular is critical. While significant efforts have been put towards documenting baseline coastal information across Canada’s southern regions, there is a large information gap regarding Arctic shorelines. Baseline coastal information such as shoreline form, substrate and vegetation type, is required for operational prioritization, coordination of on-site spill response activities (i.e., SCAT: Shoreline Cleanup and Assessment Technique), as well as providing valuable information for wildlife and ecosystem management. A standardized methodology was developed to map shoreline characteristics at six study sites across the Canadian Arctic: James Bay, Resolute Bay, Hudson Bay, Labrador Coast, Victoria Strait, and Beaufort Sea. Geo-referenced high definition videography was collected during the summers of 2010 to 2012 along coastlines within the study sites. Detailed information (i.e. shoreline type, substrate, form, height, slope, fetch, access type, exposure, etc.) describing the upper intertidal, supratidal, and backshore zones was extracted from the video and entered into a geospatial database using a data collection form. This information was used to delimit and map alongshore segments in the upper intertidal zone. The result is a vector dataset containing thousands of linear shoreline segments ranging in length from 200 m and 2 km long. In total, almost seven thousand kilometers of northern shorelines were mapped, including twenty five different shoreline types based on the upper intertidal zone. This information will feed into a larger ongoing project focused on Arctic coastal ecosystems as well as serve as valuable information for oil spill response planning should the need arise. This database also provides valuable information for habitat management, local shoreline planning, can feed into environmental assessments or be used to aid research site selection.

The Emergencies Science Division of ESTC provides Spills Technology Databases including Brochures, Oil Properties, Chemical Synonyms, PPA Instruments and Tanker Spills. This database contains information on the properties of various types of oils, a chemical thesaurus where one can look up synonymous chemical names, and information on over 700 tanker spills

These ice charts illustrate ice conditions at a particular moment in time. The ice information is presented using a standard international code, known as the Egg Code. The following charts are available from the Canadian Ice Service: -Daily Ice Charts -Image Analysis Ice Charts -Regional Ice Charts

Information received in response to notices published in the Canada Gazette under section 71 of the Canadian Environmental Protection Act (CEPA 1999). These notices target chemical substances of interest under the Chemicals Management Plan.
