Low-Level Radioactive Waste Management Office

The Low-Level Radioactive Waste Management Office (LLRWMO) was established in 1982 to carry out the responsibilities of the federal government for the management of historic low-level radioactive waste (LLRW) in Canada. The Office is operated by CNL through a cost-recovery agreement with Atomic Energy of Canada Limited, the federal Crown corporation that provides funding, direction and priorities for the LLRWMO.

The LLRWMO manages historic LLRW at numerous waste sites located throughout Canada and has successfully completed projects in Ontario, British Columbia, Alberta and the Northwest Territories. The Office responds to questions from the public, conducts consultation and stakeholder engagement activities and establishes partnerships to resolve LLRW issues within local communities.

The LLRWMO is committed to protecting public health and the environment, while performing its duties in a timely and cost effective manner. The LLRWMO has completed many successful remediation projects in its more than 30-year history.
