Major Projects Inventory (Economic) - Points
The Major Projects Inventory (MPI), which is published quarterly, lists all major projects that are proposed, planned or underway in British Columbia. These are projects with a capital cost of at least $20 million each within the Lower Mainland and projects valued at $15 million or more in the rest of B.C. This is a point layer.

National Long-term Water Quality Monitoring Data
Long-term freshwater quality data from federal and federal-provincial sampling sites 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. Sampling frequencies vary according to monitoring objectives. 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.
Major land uses
Major land uses illustrated on map 37 of the Revised Land Use and Development Plan (R.A.V.Q.1310.) Major land uses were determined by unit of assessment. For the purposes of representation, the evaluation units were merged by major allocation. The data was produced for the purpose of the final draft of the revised land use plan (map 37).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
Projects and Transformative Strategies Referred to the Major Projects Office
In August 2025 the Major Projects Office was launched, with the mandate to advance major projects in Canada and streamline federal regulatory project approval.This dataset was created to provide open access to key information about the projects and transformative strategies that have been referred to the Major Projects Office. This dataset can be layered with other data available on the Open Science and Data Platform. By accessing this data, users can conduct more comprehensive analyses to support evidence-based decision-making and inform regulatory processes including future impact assessments.Please visit the Major Projects Office for more information.
Turkey Lakes Watershed - Stream Water Chemistry
This dataset contains average concentrations of water chemistry collected from stream catchments C31, C32, C33, C34, C35, C37, C38, C39, C42, C46, C47, C49, and C50 in the Turkey Lakes Watershed, approximately 60 km northwest of Sault Ste. Marie, Ontario, Canada. These are average concentrations recorded from 1981-2018 in milligrams per litre (mg/L) of major ions (Ca, Mg, K, Na, SO4, Cl, NO3-N, NH4-N) and some nutrients (TP, TN) collected by the Great Lakes Forestry Centre. Samples are collected according to variable schedules such that frequency generally increased with increasing stream flow, (sampling period was shortest during spring runoff, 1-3 days, and longest during winter, 2-3 weeks). Sampling was accomplished by rinsing an appropriately cleaned 2-litre, polyethylene bottle at least 3 times with stream water followed by immersion to collect the final sample. Care was taken to not disturb the stream sediments throughout the sampling procedure. pH and conductivity testing is completed right after sampling. Other chemical analyses are completed by the Great Lakes Forestry Centre in Sault Ste. Marie within 2 weeks of collection. Sample integrity was maintained through storage in the dark at 4 degrees Celsius and analyzed at room temperature.
Visual Landscape Inventory - Screenings (Polygons)
Vegetative or non-vegetative objects alongside major roads and highways preventing passers by from seeing the surrounding landscape
Ecoregions - Ecoregion Ecosystem Classification of British Columbia
An ecoregion is an area with major physiographic and minor macroclimatic or oceanographic variation. There are 43 ecoregion in British Columbia of which 39 are terrestrial. Ecodivsions are meant to be mapped at 1:500,000 for regional strategic planning
Major Faults
The framework of the Cordilleran orogen of northwestern North America is commonly depicted as a 'collage' of terranes - crustal blocks containing records of a variety of geodynamic environments including continental fragments, pieces of island arc crust and oceanic crust.The series of maps available here are derived from a GIS compilation of terranes based on the map first published by Colpron et al. (2007) and more recently revised by Nelson et al. (2013). These maps are presented here in digital formats including ArcGIS file geodatabase (.gdb), shapefiles (.shp and related files), Google Earth (.kmz), as well as graphic files (.pdf). The GIS data includes terrane polygons and selected major Late Cretaceous and Tertiary strike-slip faults. Graphic PDF files derived from the GIS compilation were prepared for the Northern Cordillera (Alaska, Yukon and BC), the Canadian Cordillera (BC and Yukon), Yukon, and British Columbia. These maps are intended for page-size display (\~1:5,000,000 and smaller). Polygons are accurate to \~1 km for Yukon and BC, \~5 km for Alaska. More detailed geological data are available from both BCGC, USGS and YGS websites. Descriptions of the terranes, their tectonic evolution and metallogeny can be found in Colpron et al. (2007), Nelson and Colpron (2007), Colpron and Nelson (2009), Nelson et al. (2013) and references therein.The terrane map project is a collaborative effort of the BC Geological Survey and the Yukon Geological Survey.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Major Projects Inventory
Natural Resources Canada’s Major Projects Inventory published annually, provides a snapshot of major natural resource projects in Canada that are either currently under construction or are planned within the next 10 years.The inventory includes major projects that increase, extend or improve natural resource production in Canada, including new extraction projects, infrastructure projects, major processing facilities and large expansion projects. In addition, the inventory includes information on the value, timing and geographic location of projects.To be included in the inventory, projects in the energy and mining sectors must meet a minimum capital worth threshold of $50 million and electricity and forest sector projects must meet a threshold of $20 million. Also included in the inventory are clean energy and clean technology projects, which must meet a minimum capital worth threshold of $10 million.DISCLAIMER: Data is sourced from federal, provincial, and territorial databases, publicly accessible websites, and other sources, including CANOILS. Data and maps are for illustrative purposes only. Users understand that, although all efforts have been made to accurately and exhaustively compile, locate and classify projects, the authors do not guarantee the accuracy and/or the comprehensiveness of the data and assume no responsibility for errors or omissions. The routes of the proposed transmission lines and pipelines are approximations, often using only start and end points. In support of this initiative, proponents and partners are encouraged to contact Natural Resources Canada should they identify any significant errors or omissions.
