The applicant, an engineering firm, sought insurance coverage from the respondent for a professional negligence claim.
The claim arose from a reserve fund study completed in November 2013, which allegedly failed to identify a corroded lamppost.
A worker was injured in October 2015 due to the lamppost's collapse.
The insurer denied coverage based on a retroactive date exclusion clause (September 11, 2015), arguing the "incident" was the negligent study preparation (2013), which occurred before the retroactive date.
The applicant contended the "incident" was the worker's injury (2015), which occurred after the retroactive date.
The court dismissed the application, finding that the word "incident" in the exclusion clause unambiguously referred to the alleged misconduct in 2013, not the subsequent injury in 2015.
