Atomic Energy of Canada Ltd. (AECL) sought to amend its statement of claim in a long-running insurance indemnity action against Allianz Global Risks US Insurance Company (Allianz).
Allianz opposed the amendments, arguing they introduced new causes of action, were time-barred, lacked particulars, and caused prejudice due to inordinate delay and loss of evidence.
The court found that amendments related to causation theories advanced by Allianz's experts were not new causes of action, but the claim based on assignment of rights from MDS Nordion and Comstock was a new cause of action and time-barred.
The court granted leave to amend certain paragraphs, denied others, and required AECL to provide better particulars for the causation amendments to limit their scope to the theories advanced by Allianz's experts.
