The assessments layer represents all assessments undertaken under the Impact Assessment Act, including those that continue under the provisions of the Canadian Environmental Assessment Act, 2012. It includes assessments undertaken by the Impact Assessment Agency and other federal authorities as posted on the Canadian Impact Assessment Registry Internet site. The location of a given assessment included in the dataset is approximate and is based on information submitted by proponents, if applicable. More than one location may be identified for a given assessment. This dataset does not include information related to the footprint.Additional information about this dataset is available on the Canadian Impact Assessment Registry Internet site.

Major hard rock mining project in Yukon requires a detailed environmental and socio-economic assessment and various regulatory approvals. These approvals include, but are not limited to a Water Licence and a Quartz Mining Licence.A project must go through two distinct stages before mining activity can commence. First, an assessment determines whether significant adverse environmental or socio-economic effects are likely to occur. Second, a regulatory licensing approval process needs to take place.This data represents the location of Quartz Mining Licence in Yukon.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

This map data displays environmentally impacted sites in Saskatchewan with location, confirmed substance and current status.The Ministry of Environment is responsible for regulating environmentally impacted sites in Saskatchewan to protect the environment and the public.  An environmentally impacted site is an area of land or water that contains a substance that may cause or is causing an adverse effect.An adverse effect is an impairment of or damage to the environment or harm to human health caused by any chemical, physical or biological alterations or any combination of them.Please note: information may take up to 30 days to be updated and is subject to change at any time.For further information, please contact the Ministry of Environment Inquiry Centre (Toll Free): 800-567-4224, centre.inquiry@gov.sk.ca or visit the environmentally impacted sites page on Saskatchewan.ca. Terms and definitionsObject ID: An internal GeoHub record ID number. This number can be ignored.  Case ID: The Case ID is the ministry’s file number – a unique identifier. It is NOT the date the site became impacted.  Status – The stages of management for an environmentally impacted site.   Notification: The ministry has received notification that pollutants have been discovered at the site.  The concentration of this pollutant exceeds the threshold outlined in the Saskatchewan Environmental Code and must be reported. The pollutants may cause an adverse effect to the environment or human health. The ministry has been made aware of this and has determined that the site is an environmentally impacted site. Assessment: The site is currently undergoing, or has recently completed, analysis to determine the cause, nature or extent of potential or existing adverse effect (e.g. a Phase 2 Environmental Site Assessment). Corrective Action Plan: The site is currently undergoing, or has recently completed, activity that aims to prevent, minimize, mitigate, remedy or reclaim adverse effects (e.g. removal of impacts by excavation). Closure: This is a historical status term for environmentally impacted sites that is no longer used. The Notice of Site Condition status replaces the former status of Closure. It indicates that corrective actions have been completed at the site, endpoints have been achieved and an updated environmental status of the site has been provided to the ministry. However, no application has been made for a Notice of Site Condition certificate.  Notice of Site Condition: The ministry is satisfied that an acceptable risk level exists for the area of the site addressed in the corrective action plan. Confirmed substance: The substances of concern at the site. Examples that may cause an adverse effect are petroleum hydrocarbons, toxic metals, air pollutants, acids and solvents.

The dataset contains projects that are currently, or have been, subject to environmental assessment review. Attributes include the project description, project phase, decision, and proponent name. This layer consists of points themed two ways: a. Project Phase- This theme consists of layers showing what phase each project is in - pre-EA, application review, post-decision, and withdrawn or terminated; and b. Project Type - This theme consists of nine layers that reflect the potential types of projects under review. This dataset is coming from the EAO Project Information Centre (EPIC) and is updated daily. For more information on any of the project points go to https://projects.eao.gov.bc.ca/.

This dataset is a combination of landscape unit, biogeoclimatic zone/subzone/variants and Cariboo Chilcotin Land Use Plan (CCLUP) leading group type (PineGroup or FirGroup) used to roll up seral stage assessments in the Cariboo Natural Resource Region. Refer to the **Cariboo Regional Biodiversity Conservation Strategy Update Note #2: Amalgamation of Small NDT-BEC Units in Relation to Assessment of Seral Objectives and Old Growth Management Area Planning** and **Cariboo Regional Biodiversity Conservation Strategy Update Note #3: Definition of the Fir Group and Pine Group for Purposes of Seral Stage Assessments within NDT 4 of the Cariboo-Chilcotin** (see below under "Related Links") for more information on how seral stage assessment amalgamation units are derived.

**PLEASE NOTE:** The Environmental Monitoring System will be replaced by the EnMoDS system on March 5th, 2026. The EMS results objects will not contain new data after Feb 26th, 2026.

The dataset represents known concentration areas of harvested or unharvested Softshell clam (Mya arenaria) in the intertidal zone of the Estuary and the Gulf of St. Lawrence, Quebec region. The dataset was created for the National environmental emergencies centre (NEEC) for preparation and response in case of an oil spill. Concentration areas were defined using Fisheries and Oceans Canada (DFO) inventories conducted between 2000 and 2020.This layer is dependent on the inventories carried out and thus only represents known clam areas. For example, for the Haute-Côte-Nord, inventories have been limited to areas open to harvesting (with the exception of 4 sectors), but it is known that the Softshell clam is also present outside these areas. In addition, little information was available for the Moyenne and Basse-Côte-Nord.This data layer does not represent the general distribution of the species nor the extent to which fishing is allowed. The extent of shellfish beds may vary over time in response to, among others harvesting and the recruitment rates. The boundaries of polygons from inventory data may be underestimated relative to the actual size of the deposit since the inventories were conducted at the location where the resource is most abundant, without necessarily sampling the entire bed. However, the accuracy is sufficient for the protection and management needs of the resource in the event of an environmental incident. Data sources and references:Brulotte, S. 2011.

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.
