This dataset consists of information from reports received by the Spills Action Centre (SAC). They are generated and completed by SAC following the initial report of a spill. The data includes: * the reference number assigned to the spill * the municipality in which the spill occurred * what was impacted (e.g. land, water, air, or combination) * the substance being discharged (e.g. oil, gases, chemical, etc.) * whether the environmental impact is confirmed, possible, or not anticipated, and * the source/sector of the spill. The data reflects the information as reflected in the report, following the incident. All spills reported to SAC are recorded in the database, regardless of whether or not the Ministry provides field response.

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.

Historical Oil Fields are subsurface accumulations or 'pools' of crude oil designated as such for the purposes of the Oil, Gas and Salt Resources Act. This product requires the use of geographic information system (GIS) software.

Land Plats illustrate in map view the oil or gas Spacing Areas delimited in a pool, and names the geological formation in which the pool is recognised. Land Plats are the sole official record of where the Director of PandNG Titles Branch recognizes a pool of hydrocarbons to exist for the purpose of administering oil and gas title

A literature review, focusing on oil sand products (e.g., diluted bitumen), diluents, spill-treating agents, and crude oil toxicology and ecological studies, relevant to the northeast Pacific was compiled as part of the Government of Canada’s World Class Tanker Safety program. Of the 763 references identified, 14 involved diluted bitumen and other heavy crude oils, indicating the need for further research of these products in the marine environment. Diluent research suggests relatively fast evaporation and dispersion times for this component, however high toxicities may pose a threat to marine biota. Historical studies indicate older dispersant formulations had potential ecological implications, therefore newer formulations, which have not been studied in detail, require full assessment. Consistent utilization of toxicology standards remains elusive, hindering species sensitivity analyses. Exxon Valdez literature demonstrates highly variable impacts from a single oil type and the need for baseline data, recovery status, and suitable ecological end-point determination.
