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.

This dataset is provided by the Ministry of Affordability and Utilities, Electricity Sustainability and Innovation Branch, and identifies the high-quality agricultural lands, buffer zones, and visual impact assessment zones in Alberta designated under the Electric Energy Land Use and Visual Assessment Regulation (EELUVAR) made under the Alberta Utilities Commission Act. These areas apply to applications for the construction or operation of power plants under Alberta Utilities Commission Rule 007, unless exempted under the regulation. Restrictions on development of high-quality agricultural land are limited to privately owned land as per the regulation. This data product includes the following datasets: Land Suitability Rating System (LSRS) Class 2 and Class 3H Lands, Visual Impact Assessment Zones, and Buffer Zones. Visual Impact Assessment Zones and Buffer Zones contain both private and public lands.

Study Area defined in the Agreement to Conduct a Regional Assessment of Offshore Wind Development in Nova Scotia. The study area was created by the Impact Assessment Agency of Canada in collaboration with Natural Resources Canada and the province of Nova Scotia.

Study Area defined in the Agreement to Conduct a Regional Assessment of Offshore Wind Development in Newfoundland and Labrador. The study area was created by the Impact Assessment Agency of Canada in collaboration with Natural Resources Canada and the province of Newfoundland and Labrador.

Fisheries and Oceans Canada has conducted a cumulative human impact mapping analysis for Pacific Canada to support ongoing Marine Spatial Planning. Cumulative impact mapping (CIM) combines spatial information on human activities, habitats, and a matrix of vulnerability weights into an intuitive relative ‘cumulative impact score’ that shows where cumulative human impacts are greatest and least. To map cumulative impacts, a recently developed ecosystem vulnerability assessment for Pacific Canadian waters (Murray et al. 2022) was combined with spatial information on thirty-eight (38) different habitat types and forty-five (45) human activities following the methodology from Halpern et al.(2008) and Murray et al. (2015). The cumulative impact map is provided in a 1x1 km grid used for oceans management by Fisheries and Oceans Canada. For further information, please contact the data provider.

This geospatial data depicts preliminary offshore wind licencing areas recommended by the Committee for the Regional Assessment of Offshore Wind Development in Newfoundland and Labrador (Committee). These areas were identified as an interim product during the Regional Assessment process. The Committee is tasked to complete its Regional Assessment Report by January 2025. As part of the terms of amended agreement set out by the Governments of Canada and Newfoundland and Labrador, the Committee submitted an interim report to Ministers on March 22, 2024. This report included a preliminary map of recommended areas for offshore wind. Based on work completed to date, the Committee has found these areas are where offshore wind development is most likely feasible and will have the least impact within offshore Newfoundland and Labrador. These areas are preliminary and will be refined throughout the remainder of the Regional Assessment. Through the Regional Assessment process, the Committee is providing federal and provincial Ministers with information, knowledge, and analysis regarding future offshore wind development. Their work is intended to inform and improve future planning, licencing, and impact assessment processes. Any offshore wind areas identified by the Committee do not reflect official offshore wind licencing areas. The Committee is providing these areas to Ministers for their consideration, as the offshore wind regulatory process is being established.

The Drought Impact Lines dataset highlights areas that have been physically impacted by drought. All drought impact lines have a drought impact label inside of them to express the longevity of the impact.The impact lines are classified using impact labels as follows:S – Short-Term, typically less than 6 months.L – Long-Term, typically more than 6 months.SL – A combination of Short and Long-Term impacts.

The Standardized Precipitation Evapotranspiration Index (SPEI) is computed similarly to the SPI. The main difference is that SPI assesses precipitation variance, while SPEI also considers demand from evapotranspiration which is subtracted from any precipitation accumulation prior to assessment.Unlike the SPI, the SPEI captures the main impact of increased temperatures on water demand.

This geospatial data depicts potential development areas (PDAs) recommended by the Committee for the Regional Assessment of Offshore Wind Development in Nova Scotia.The Committee for the Regional Assessment of Offshore Wind Development in Nova Scotia (Committee) provides federal and provincial Ministers with information, knowledge, and analysis regarding future offshore wind (OSW) development in Nova Scotia. Its work is intended to inform and improve future planning, licencing, permitting, and impact assessment processes.Under the Terms of Reference, the Committee submitted an interim report to Ministers on March 23, 2024. This report included the preliminary identification of recommended areas for potential future development areas (PFDAs) for offshore wind. Based on work completed since the interim report, the Committee issued its final report on January 23, 2025, which included refined development areas, the Potential Development Areas (PDAs). These PDAs are based on technical feasibility (using available information) and have the least impact on other offshore users. It should be noted that the PDAs are recommendations only and do not reflect official offshore wind energy areas.

The Drought Impact Label dataset is used on all drought polygons from D1 to D4 to specify the longitude and magnitude of impacts. Impact labels are often used in association with the Drought Impact Line dataset.The impact labels are classified as follows:S – Short-Term, typically less than 6 months.L – Long-Term, typically more than 6 months.SL – A combination of Short and Long-Term impacts.
