30-year Average Number of Days with Temperature above 25 °C are defined as the count of the number of climate days during the month where the maximum daily temperature was greater than 25 °C. These values are calculated across Canada in 10x10 km cells.

The National Ecological Framework for Canada provides a consistent, national spatial framework that allows various ecosystems to be described, monitored and reported on. It provides standard ecological units that allow different jurisdictions and disciplines to use common communication and reporting, and a common ground to report on the state of the environment and the sustainability of ecosystems in Canada. The framework was developed between 1991 and 1999 by the Ecosystems Science Directorate, Environment Canada and the Center for Land and Biological Resources Research, Agriculture and Agri-Food Canada. Over 100 federal and provincial agencies, non-governmental organizations and private sector companies contributed to its development.

This data series was compiled by AAFC and Statistics Canada using a combination of agroclimate data and satellite-derived Normalized Difference Vegetation Index (NDVI) data for the current growing season. The forecast is made based on a statistical model using historical yield, climate and NDVI data.

In 1949 a magnitude 8.1 earthquake occurred on the Queen Charlotte Fault, off the west coast of the Haida Gwaii archipelago. This magnitude 7.7 scenario along the Queen Charlotte Fault is slightly different and closer to population centres than the magnitude 7.8 earthquake that occurred in 2012.

Catch, effort, location (latitude and longitude), and associated biological data from the Eulachon Migration Study Bottom Trawl surveys on the coast of British Columbia. Introduction: The Eulachon Migration Study Bottom Trawl surveys are divided into two parts; the Eulachon Migration Study Bottom Trawl – South (Eul –S) and the Eulachon Migration Study Bottom Trawl – North (Eul-N). The objectives of these surveys were to learn about the distribution, ecology, and migration timing of Eulachon into and out of the Fraser (Eul-S), Nass, and Skeena River (Eul-N) systems. This was achieved by observing Eulachon spatial and temporal occurrence and biological condition over a wide survey region each month. EUL-S covered portions of the Strait of Georgia and Juan de Fuca Strait in Pacific Fishery Management areas (PFMA’s) 17-20, 28, 29, and 121. There were nine trips conducted from October 2017 to March 2018 and one trip in January 2019. Eul-N consists of seven trips conducted between July 2018 and March 2019 mainly in Chatham Sound with sets in Hecate Strait, and Portland Inlet (Pacific Fishery Management areas (PFMA’s) 3, 4, and 104). Fishing was conducted using the Canadian Coast Guard Research Vessel Neocaligus to tow an American shrimp trawl net (Cantrawl Nets Ltd., Richmond, BC). The horizontal opening of the polypropylene net was estimated to be 34 to 37 feet (10 to 11 m), while the center of the opening had a vertical height of approximately 7 to 9 feet (2 to 3 m). A 0.4” (10 mm) liner was used in the codend. The net was configured with roller gear and 72” (1.8 m) Thyboron Type 2 trawl doors. Tow duration was typically 20 minutes for Eul-S and ranged from 5-20 minutes for Eul-N. The standard hours of fishing were 0700 to 1700 hours, depending on sunrise and sunset in winter months. These surveys follow a random block design in a targeted depth range of 80 – 200 metres for the Eul-S and 80-300 metres for Eul-N. The surveys were conducted by the Department of Fisheries and Oceans Canada (DFO) and was funded by the Fisheries and Oceans Canada (DFO) National Rotational Survey Fund.

30-year Average Number of Days with Temperature above 30 °C are defined as the count of the number of climate days during the time period where the maximum daily temperature was greater than 30 °C. These values are calculated across Canada in 10x10 km cells.

A magnitude 5 earthquake scenario along an unnamed fault located about 15 km north-northeast of Burnaby City Hall and directly south of Mt Elsay. This fault is not known to be active, but this scenario represents a small but damaging event in the North Shore Mountains.

Ottawa planning scenario using the 2010 Val-de-bois, QC earthquake hypocentre and fault plane geometry from Ma & Motazedian, 2012 and Atkinson & Assatourians, 2010. This scenario uses a larger magnitude event than those that have been observed to date for that location, within bounds of the national seismic hazard model. Maximum magnitude of 7.95 is obtained from CanSHM6 for GATINEAU region.

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.

Statistically downscaled multi-model ensembles of projected change (also known as anomalies) in maximum temperature (°C) are available at a 10km spatial resolution for 1951-2100. Statistically downscaled ensembles are based on output from twenty-four Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models (GCM). Daily maximum temperature from GCM outputs were downscaled using the Bias Correction/Constructed Analogues with Quantile mapping version 2 (BCCAQv2). A historical gridded maximum temperature dataset of Canada (ANUSPLIN) was used as the downscaling target. Projected change in maximum temperature (°C) is with respect to the reference period of 1986-2005. Seasonal and annual averages of projected maximum temperature change to 1986-2005 are provided. Specifically, the 5th, 25th, 50th, 75th and 95th percentiles of the downscaled ensembles of maximum temperature change are available for the historical time period, 1901-2005, and for emission scenarios, RCP2.6, RCP4.5 and RCP8.5, for 2006-2100. Twenty-year average changes in statistically downscaled maximum temperature (°C) for four time periods (2021-2040; 2041-2060; 2061-2080; 2081-2100), with respect to the reference period of 1986-2005, for RCP2.6, RCP4.5 and RCP8.5 are also available in a range of formats. The median projected change across the ensemble of downscaled CMIP5 climate models is provided. Note: Projections among climate models can vary because of differences in their underlying representation of earth system processes. Thus, the use of a multi-model ensemble approach has been demonstrated in recent scientific literature to likely provide better projected climate change information.
