As you know, AECL delivers its mandate through a GoCo model, whereby the operations of its nuclear laboratories, including decommissioning and waste management work, are delivered by Canadian Nuclear Laboratories. Under this model, AECL continues to own the land, facilities, assets, and liabilities, whereas the workforce, the licences, and all other aspects of the running of the sites are part of Canadian Nuclear Laboratories' business. AECL is a small crown corporation whose role is to oversee the contract with Canadian Nuclear Laboratories and act as a smart buyer on behalf of the government in order to bring value for money to Canadians.
