The applicant, Her Majesty the Queen in Right of Ontario, sought a declaration that the respondent, Turn-Key Construction Inc., had a contractual duty to defend Ontario in an action commenced by a third party, G. Prezio Electric Limited.
The underlying action arose from Turn-Key's subcontractor severing a major electrical power line during contract performance, leading Ontario to engage Prezio for emergency repairs.
The court found that the indemnity clause in the commercial contract between Ontario and Turn-Key created a duty to defend, as the third-party claim was "based upon, occasioned by or attributable to" the subcontractor's actions.
The application was granted, and Turn-Key was ordered to pay Ontario's defence costs.
