Data-center law in Canada
National jurisdiction · as of 2026-09-02
No federal statute permits or specifically regulates data center siting in Canada. Land use, zoning and construction permitting are provincial and municipal matters under the Constitution Act, 1867's grant of property and civil rights and municipal institutions to the provinces, so the state-level pages, not this one, carry that ground.
Federal law reaches a data center project only through overlays: the Impact Assessment Act where a project is a designated project or otherwise triggers a federal decision, and the Canadian Energy Regulator Act where the project's power supply involves an international or interprovincial power line. A stand-alone data center is not itself a listed activity under either Act, and as of the date shown no data-center-specific federal permitting statute is in force.

Instruments on record
2 instruments on record, grouped by the family of approval each one governs.
Environmental review
What impact review must precede approval, and who leads it?
Impact Assessment Act
In force
S.C. 2019, c. 28, s. 1
Effective 2019-08-28 · Applies to both
Requires an impact assessment for a designated project, defined as one or more physical activities carried out in Canada or on federal lands that are designated by regulations made under the Act or by ministerial order.
A stand-alone data center is not itself a listed physical activity under the Physical Activities Regulations, so most private data-center projects on private, non-federal land never trigger a federal impact assessment; a project connected to a designated activity such as major transmission infrastructure or carried out on federal lands can still be drawn in.

Energy and grid
What authorizations govern grid connection and onsite generation?
Canadian Energy Regulator Act (international and interprovincial power lines)
In force
S.C. 2019, c. 28, s. 10, Part 4
Effective 2019-08-28 · Applies to both
Most electric power lines and facilities fall within provincial jurisdiction, but the Canadian Energy Regulator authorizes the construction and operation of international power lines (crossing the Canada-U.S. border) and interprovincial power lines designated under section 261 of the Act.
A data center's local grid connection is ordinarily a provincial or utility matter; federal jurisdiction attaches only where the specific transmission facility crosses a provincial or international boundary and is designated under this Act.
