Country
Canada
A relatively small intelligence community led by the Canadian Security Intelligence Service (CSIS) and the Communications Security Establishment (CSE), with a founding role in the Five Eyes signals partnership.
Canada's intelligence community is anchored by the Canadian Security Intelligence Service (CSIS), created by statute in 1984 to separate intelligence work from the Royal Canadian Mounted Police following the McDonald Commission's findings on RCMP Security Service abuses. The Communications Security Establishment (CSE), originally a unit of the Department of National Defence dating to 1946, is the signals-intelligence and cyber-security agency and one of the founding partners of the UKUSA / Five Eyes signals arrangement. The Canadian Forces Intelligence Command (CFINTCOM) is the principal military-intelligence service.
Canadian intelligence operates under one of the more developed accountability frameworks in any comparable jurisdiction, including the National Security and Intelligence Committee of Parliamentarians (NSICOP), established 2017; the National Security and Intelligence Review Agency (NSIRA), established 2019; and the Office of the Communications Security Establishment Commissioner (now consolidated into NSIRA). Successive public crises — the McDonald Commission of the 1970s, the Air India bombing of 1985 and the subsequent inquiry, the Maher Arar case and Iacobucci Inquiry, and the post-2014 review of CSIS threat-reduction authorities — have shaped the current statutory framework.

How to read a country page
This is the institutional landscape of Canada's intelligence apparatus as it is documented in the public record. Each card above links through to a full agency profile — the service's founding date, statutory basis, jurisdiction, parent ministry, headquarters, official channels, and a structured account of role, history, and notable operations footnoted to primary sources. The agencies on this page may overlap institutionally (a foreign-intelligence service and a signals-intelligence service often share missions and personnel) and may operate against one another in counter-intelligence terms; the country page does not impose a hierarchy among them, only an inventory.
If a particular operation or scandal is what you are looking for rather than the institutional background, see the Dossiers — long-form pieces that cross agencies and countries. The methodology page documents how operations are categorised as confirmed, alleged, or disputed, and what the public record can and cannot tell us. The Lexicon defines the terms that recur across these pages — HUMINT, SIGINT, covert action, plausible deniability, station, asset, finding.
Coverage here grows as new declassifications expand what can responsibly be said about services that remain partly closed. Some agencies have full reference entries; others are stub entries pending the full treatment. Stubs are kept on the index so navigation between related services is preserved while the detailed text is written.
