Supreme Court of Canada Dismisses Appeal in Jurisdiction Dispute Involving Third Party Claims

The Supreme Court of Canada has ruled that third party claims against lawyers practicing in Quebec can proceed in Ontario.

July 20, 2016

Peter H. Griffin acted as counsel to the successful respondents in an appeal before the Supreme Court of Canada about whether the Ontario courts had properly assumed jurisdiction over a third party claim brought by the respondents against numerous lawyers practicing in Quebec.  The third party claim arose in the context of a national class action.

The Supreme Court dismissed the Quebec lawyers' appeal of the decision of the Court of Appeal for Ontario.  The majority of the Supreme Court held that the Ontario courts properly assumed jurisdiction over the third party claim, as a contract connected with the dispute was made in Ontario.  The majority also held that no other forum would be fairer or more efficient in the circumstances.
