Under section 2 of the Nuclear Safety and Control Act (NSCA), radioactive waste in Canada is defined as any material (liquid, gaseous or solid) that contains a radioactive nuclear substance for which no further use is foreseen. In addition to containing nuclear substances, radioactive waste may also contain hazardous substances that are not radioactive, as defined in section 1 of the General Nuclear Safety and Control Regulations.

Oversight and management of Canada’s radioactive waste
High-level radioactive waste (HLW) is used (irradiated) nuclear fuel whose owners have declared it as radioactive waste and/or which generates significant heat through radioactive decay.
In Canada, low- and intermediate-level radioactive waste refers to all forms of radioactive waste, except used nuclear fuel, limited waste from the production of medical isotopes, and the waste from uranium mining and milling.
The main types of waste generated by the mining and milling of uranium ore are tailings and waste rock.
Historic low-level waste consists of soil contaminated with uranium and radium, at sites located in the Northwest Territories, British Columbia, Alberta and Ontario.
The bulk of Canada's historic waste is located in the Ontario communities of Port Hope and Clarington.
The low-level contamination in the Toronto area comes from production of radioluminescent dials.
From the early 1930s to the 1950s, uranium ore was transported over 2,200 km by the Northern Transportation Route (NTR) from Port Radium (on Great Bear Lake, Northwest Territories) to the railhead at Waterways (now Fort McMurray, Alberta).
A deep geological repository is constructed underground, usually at a depth of several hundred metres or more below the surface in a stable rock formation.
