Today, the Canadian Nuclear Safety Commission (CNSC) announced the decisions on the reviews of 2 orders issued to Best Theratronics Ltd. in response to regulatory non-compliance at its medical device manufacturing facility in Ottawa, Ontario:

On November 6, 2024, a CNSC designated officer issued an order to Best Theratronics Ltd. for non-compliance with its licence condition to maintain an acceptable financial guarantee for decommissioning.  On February 14, 2025, this order was largely confirmed by the Commission and was amended to clarify the requirements for the financial guarantee. The amended order will be in place until the licensee satisfies the requirements for the financial guarantee.

On November 8, 2024, following an inspection of the facility, a CNSC inspector issued an order related to Best Theratronics Ltd.’s security and emergency preparedness programs. The order required the licensee to put additional security and emergency preparedness measures in place. On February 14, 2025, this order was amended by a CNSC Designated Officer to reflect the licensee’s progress in addressing the items raised in the original order. The amended order will be in place until the licensee complies with the remaining actions.  

There is no risk to the public or the environment stemming from either non-compliance. The financial guarantee order requires the licensee to not operate under its Class IB licence until a financial guarantee acceptable to the Commission is established and an acceptable plan to restart operations is provided. Nuclear substances on site continue to be stored safely. 

The licensee exercised its right to be heard as part of the review of both orders.
