There are fourteen major and four minor field trial regions in Canada and USA. Each of these regions recognizes physical characteristics, such as soils, and crops and climate, that make the region unique. The subzones address differences within a region, generally reflected in the types of crops grown in that region. The Canadian regions, as much as possible, correspond to the U.S. regions. The trial regions contain number of field trials by specific crop.

The Canadian major and minor crop field trial regions were developed following extensive stakeholder consultation and have been harmonized between the Pest Management Regulatory Agency (PMRA) and the Environmental Protection Agency of the USA. The Canadian major and minor crop field trial regions were delineated, using the geographic information system (GIS) data processing hardware and software facilities in Spatial Analysis and Geomatics Applications (SAGA), Agriculture Division, Statistics Canada. In general, the delineation process involved integration, evaluation and reference to numerous geographic data sources in a GIS to determine the best sources for the delineation. There are seven major and four minor field trial regions. Each of these regions recognizes physical characteristics, such as soils, and crops and climate, that make the region unique within the Canadian agricultural landscape. The subzones address differences within a region, generally reflected in the types of crops grown in that region. The Canadian regions, as much as possible, correspond to the U.S. regions

The Canadian major and minor crop field trial regions were developed following extensive stakeholder consultation and have been harmonized between the Pest Management Regulatory Agency (PMRA) and the Environmental Protection Agency of the USA. The identified regions are used for experimental studies in support of residue chemistry data requirements for the registration of new pesticide uses. The regions are based on soil type and climate and do not correspond to plant hardiness zones.

Long-term freshwater quality data from over 200 federal and federal-provincial sampling sites at various locations and sampling frequencies throughout Canada's aquatic ecosystems are included in this dataset. Measurements regularly include physical-chemical parameters such as temperature, pH, alkalinity, major ions, nutrients and metals. Collection includes data from active sites, as well as historical sites that have a period of record suitable for trend analysis. The number of sites in the network varies slightly from year-to-year, as sites are adjusted according to a risk-based adaptive management framework. The Great Lakes are sampled on a rotation basis and not all sites are sampled every year. Data are collected to meet federal commitments related to transboundary watersheds (rivers and lakes crossing international, inter-provincial and territorial borders) or under authorities such as the Department of the Environment Act, the Canada Water Act, the Canadian Environmental Protection Act, 1999, the Federal Sustainable Development Strategy, or to meet Canada's commitments under the 1969 Master Agreement on Apportionment./Les données de monitoring de la qualité de l'eau douce à long terme de plus de 200 sites d'échantillonnage fédéraux et fédéraux-provinciaux à diverses stations et fréquences d'échantillonnage à travers les écosystèmes aquatiques du Canada sont incluses dans cet ensemble de données. Les mesures incluent régulièrement les paramètres physico-chimiques tels que la température, le pH, l'alcalinité, les ions majeurs, les nutriments et les métaux. La collection inclut des données des sites actifs, ainsi que des sites historiques qui possèdent une période d'enregistrement propice à l'analyse des tendances. Le nombre de sites dans le réseau varie légèrement d'une année à l'autre, puisque les sites sont ajustés selon un cadre de travail de gestion adaptative basée sur le risque. Les Grands Lacs sont échantillonnés sur une base rotationnelle et tous les sites ne sont pas échantillonnés à chaque année. Les données sont recueillies afin de rencontrer les engagements fédéraux relatifs aux bassins versants transfrontaliers (rivières et lacs traversant des frontières internationales, interprovinciales et territoriales) ou sous certaines autorités telles que la Loi sur le ministère de l'Environnement, la Loi sur l'environnement, la Loi sur les ressources en eau du Canada, la Loi canadienne sur la protection de l'environnement de 1999, la stratégie fédérale de développement durable, ou pour rencontrer les engagements du Canada dans le cadre de l'Accord cadre sur la répartition des eaux des Prairies de 1969.
