The appellants purchased railway land in Niagara Falls from Canadian National Railway Company (CN) in 2008, with CN taking back a mortgage.
The appellants defaulted and CN sued.
The appellants brought a third-party action against their solicitors (McMillan LLP, Philip Thompson, and Marssa Giahi) for negligence, claiming they failed to properly advise about a Director's order under the Environmental Protection Act registered on title.
The respondents obtained summary judgment dismissing the third-party claim.
The appellants appealed, arguing the motion judge erred in applying Rule 20 principles and that genuine issues for trial existed regarding the duty of care, knowledge of the Director's order, and causation.
The Court of Appeal upheld the summary judgment, finding no negligence claim against McMillan due to lack of involvement in the final transaction, and no duty to warn Thompson and Giahi given the "as is" agreement and client's explicit instructions not to investigate environmental concerns.
