Canada has the longest coastline in the world, measuring 243,790 kilometers. Many of our waterways along the coastline have to be dredged regularly to keep shipping channels and harbours open and safe for navigation; and this material is sometimes best disposed of at sea. Schedule 5 of the Canadian Environmental Protection Act, 1999 (CEPA) defines an exclusive list of materials and substances suitable for disposal at sea in Canada, which is in accordance with the London Protocol (1996). They are: dredged material, fish waste resulting from industrial fish processing operations, ships or platforms, inert and inorganic geological matter, uncontaminated organic matter of natural origin, and bulky substances. The disposal of any substance into the sea, on the seabed, in the subsoil of the seabed, or onto ice, from a ship, an aircraft, a platform or other structure is not allowed unless a permit is issued by the Environment and Climate Change Canada (ECCC) Disposal at Sea Program. Incineration at sea, as well as importing or exporting a substance for disposal at sea is also prohibited. More information on Disposal at Sea is available at: https://www.canada.ca/en/environment-climate-change/services/disposal-at-sea.html The Active Disposal at Sea Sites in Canadian Waters dataset provides spatial and related information of at-sea disposal sites approved for use in Canada in the last ten years. Any additional use of a disposal site must be conducted in accordance with the terms and conditions of a valid Disposal at Sea permit. The dataset may be of use in relation to Disposal at Sea permit applications. For some Disposal at Sea permit applications the data may be of use in assessing serious harm to fish under the Fisheries Act and assessing interference with navigation under the Navigation Protection Act.

This dataset was created to provide a spatial dataset of the school divisions within the province of Manitoba.This polygon layer depicts official boundaries of the Manitoba School Divisions as per Director of Surveys (DoS) plans. Each DoS number can be found in the field "source". Boundaries are approved by both Manitoba Education and the Director of Surveys of Manitoba. Ward boundaries, schools and the following school divisions are not included in this dataset: Funded Independent,  Non-funded Independent,  First Nations,  Institutional schools, and  The Division Scolaire franco-manitobaine. This  polygon layer is symbolized by the School Division Names in the field SchoolDiv.The dataset includes the following fields:Alias (Field Name): Description of fieldFID (FID): Identification numberOBJECTID (OBJECTID): Object IDShape Length (Shape_Leng): Length of polygonShape Area (Shape_Area): Area of polygon shapeSchool Division Name (School_Div): Division Name.DoS Source Number (SOURCE): Director of Surveys (DoS) plan number.Website (WEBSITE): Division website address (if available).

This polygon dataset shows First Nation land acquisitions designated as Other Land as outlined by the Treaty Land Entitlement (TLE) Agreements in Manitoba, pursuant to the Crown Lands Act 5(1)(d).The purpose of this dataset is to show geographic boundaries for land acquisitions designated as Other Land, as outlined by the Treaty Land Entitlement (TLE) Agreements in Manitoba, pursuant to the Crown Lands Act 5(1)(d). This is a dynamic dataset - data can change daily.Other Land includes land that has been purchased by the First Nations from private landowners or Surplus Provincial or Surplus Federal land that has been purchased from the Manitoba or Canada governments. The title to the land is privately held by a First Nation corporation until it gets transferred to the Government of Canada, however the mines and minerals and other residual interests may be owned by the Crown (Government of Manitoba) and they are required to be transferred to the Government of Canada (subject to third party interest resolution, if applicable).The sites are generally identified by title with reference to a plan of survey, metes and bounds description. Locations are mapped using existing cadastral or parcel mapping data, or reasonably illustrate the site within the dataset. A record may contain multiple polygons that have been combined to form one record.All boundaries are to be considered approximate and for illustrative purposes only.For more information on Treaty Land Entitlement (TLE) Agreements please visit the Manitoba government website: https://www.gov.mb.ca/inr/treaty-land-entitlement/index.htmlFields included [Alias (Field Name): Field description]OBJECTID (OBJECTID): Sequential unique whole numbers that are automatically generatedSite ID (SITE_ID): Site ID number of the selected siteArea in Square Metres (AREA): Area in square metresArea in Acres (ACREAGE): Area in acresBand Council Resolution Number (BCR_NO): Band Council Resolution numberName of the First Nation Making the Land Selection (BAND_NAME): Name of the First Nation making the land selectionSite Number (SITE_NO): Site number of the selected siteSelection Name (SELECTION): Name of the selected site

The layer provides information on suspended particulate matter (SPM) concentrations by area. There is a natural interaction phenomenon between hydrocarbons and SPM, that creates hydrocarbon-SPM aggregates. The SPM in the water column, hence has an effect on hydrocarbon capacity to sink to the bottom in aggregate form (Gong et collab., 2014 ; Fitzpatrick et collab., 2015, cited in Centre d'expertise en analyse environnementale du Québec, 2015). Additional InformationThe suspended particulate matter data for this layer are derived from multiple sources given the need to cover the St. Lawrence portion from Montreal to Anticosti. The layer has been cut into 6 different zones. Denis Lefaivre, a researcher at Maurice-Lamontagne Institute, has provided the coordinates of the points allowing the delimitation of areas. The values in each zone are derived from different studies carried out at different times.

A "contaminant attenuation zone" is a three-dimensional zone that is, * located on land adjacent to a landfilling site, * in the subservice or extends into the subsurface, and * is used or is intended to be used for the attenuation of contaminants from the landfilling site to levels that will not have an unacceptable impact beyond the boundary of the zone. This product requires the use of geographic information system (GIS) software.
