Law360 Canada ( November 5, 2025, 9:37 AM EST) -- Appeal by Grant Thornton LLP (Grant Thornton) from chambers judge’s decision striking third party notice. Two of the limited partners in a real estate development, Interior Equities Corp. and KF Capital Ltd., sued the general partner, Cadence at the Lake Management Ltd. (CLM), claiming that CLM took certain steps that caused prejudice to their position. Burnet, Duckworth & Palmer LLP, and one of the firm’s lawyers, the respondent Denise McMullen (collectively, the Lawyers), drafted the Partnership Agreement and an Amendment thereto. Faced with legal proceedings brought by the limited partners, CLM initiated third-party proceedings against the Lawyers. Grant Thornton were CLM’s accountants and financial advisors. Faced with CLM’s claims against them, the Lawyers issued their own third party notice to Grant Thornton, seeking contribution and indemnity pursuant to the Negligence Act. In proceedings in the court below, the appellant Grant Thornton applied to strike the third party notice. The chambers judge dismissed the application. On appeal, Grant Thornton contended that the chambers judge erred in allowing the third party notice to stand by assessing the claim based on facts that were not pleaded in the third party notice. They also argued the chambers judge erred in failing to recognize that the Lawyers’ claims against Grant Thornton were obligations belonging to CLM, which the Lawyers could have raised directly against CLM, thereby making a third party notice unnecessary....
