The Alberta Court of Appeal has affirmed and extended the seminal Supreme Court of Canada decision in Ledcor v. Northbridge1 regarding faulty workmanship exclusion clauses to all-risk policies more generally. In Condominium Corporation No. 9312374 v.

This resulted in damage to the structural integrity of the parkade.

The Condominium Corporation applied for coverage for the property damage under their all-peril property policy. The policy contained the commonly found faulty workmanship exclusion which excluded coverage for the cost of making good faulty or improper workmanship. The faulty workmanship exclusion also contained the common exception to the exclusion - providing that the exclusion clause does not exclude coverage for any damage caused directly by a resultant peril not otherwise excluded.
