Every data centre in Canada built or planned for AI and high-performance computing that we can document: who runs, owns and uses it, which authority approved it and on what conditions, and how much power was requested, allocated and built. Large projects whose use is not yet stated are shown too, and all other data centres are one click away. Each fact links to its source.
AI and HPC sites: data centres with AI, GPU or high-performance computing use stated in a source, research computing clusters, and crypto-mining sites with a sourced conversion to AI. Large projects, use not stated: proposed or approved data-centre projects (mostly 50 MW or more, or of unstated type) whose proponents have not said what they will run; many are marketed for AI without saying so on the record. Other data centres: colocation, cloud, enterprise, government and crypto-mining sites, kept as context in an optional layer.
A building, or a campus at one location, that houses servers at data-centre scale for others or for its owner: colocation, cloud, AI and high-performance computing (HPC), crypto mining, and government and enterprise data centres, from first public announcement to cancellation. Carrier data centres inside telecom buildings count when the operator itself calls them data centres. Server rooms in office buildings and power plants are not sites; a plant built for a data centre appears on that data centre's record.
Operating: in service. Under construction: a dated source shows work on site has started. Approved: at least one approval needed to build has been granted (a land-use permit, a grid allocation or a power-plant approval), with no evidence of construction; the record lists which. Proposed: an application or filing exists. Announced: a public statement only. Paused, refused, cancelled as stated by the proponent or the authority.
Power is stated in different ways: IT load (what the servers draw), facility power (including cooling), a grid allocation, an amount requested in a grid-connection queue, or a planned full build-out. We show each figure with its kind and date and never add figures of different kinds. The headline numbers count sites, grid allocations and queue requests, which are comparable; stated capacity by kind is under "Stated capacity by kind". Grid queues are published by the Alberta Electric System Operator (AESO) and Ontario's Independent Electricity System Operator (IESO); Hydro-Québec publishes no queue, and Québec requires ministerial authorisation for new loads of 5 MW or more without publishing the megawatts or conditions.
"AI and HPC sites" means sites whose AI or high-performance computing use is sourced (marked yes or partly), plus research computing clusters and crypto-mining sites with a sourced conversion to AI. We do not estimate chips or computing power: operators publish too little to do it site by site without guessing. Where an operator states its chips, the site record quotes it.
Each source is tagged public record (regulator, utility, government, court, municipality, securities filing), proponent (the company's own statement), press, directory (a third-party list) or estimate (our calculation). A site's confidence is high when its status rests on a public record or the proponent's own statement, medium when it rests on press, low when it rests on a directory. A dashed outline means the point is placed at the town or region, not the building.
Not published for most sites: chips installed, training versus inference use, actual electricity and water use, and the conditions attached to Québec authorisations and British Columbia allocations. Absence from this map is not evidence that a site does not exist.
Operator pages, securities filings, utility and regulator records (AESO, IESO, Alberta Utilities Commission, Régie de l'énergie, Hydro-Québec, BC Hydro), municipal permits and government releases, cited on each site. Sites were found through PeeringDB, OpenStreetMap (ODbL), Collectif NRS and Université Laval, Alberta Data Centre Watch, Boxwood Strategy, Stop the Datacentre and commercial directories.
Write to observatory@horizonomega.org with the site, what is wrong or missing, and a source we can check (a filing, a permit, the operator's own page). Every site record has a "report a correction" link that fills in the site for you. We check each report against its source; an accepted correction appears under "What changed" with a one-line note.
