This appeal addressed whether two insurers, AIG and Lloyd's, had a duty to defend a mutual policyholder (the City of Timmins) in a progressive property damage claim.
The key issues were the role of "premature" evidence in duty to defend analysis, the interpretation of an "Expected or Intended Injury" exclusion clause, and whether a "crystallizing event" (an AMEC Report) triggered this exclusion.
The Court of Appeal upheld the application judge's decision, finding that the AMEC Report was "premature" evidence and not a "crystallizing event" that would negate Lloyd's duty to defend.
The court affirmed that the underlying claim was based on negligence, not intentional conduct, and therefore the exclusion clause did not apply, triggering Lloyd's duty to defend.
