The doctrine of forum non conveniens, in looking to identify the most appropriate forum for the litigation, considers many factors. Two of these are (i) a desire to avoid, if possible, a multiplicity of proceedings and (ii) any potential difficulties in enforcing the decision that results from the litigation. However, it is important to keep these factors analytically separate.
In the Supreme Court of Canada’s recent decision in Haaretz.com v Goldhar (available here) Justice Abella noted that “enforcement concerns would favour a trial in Israel, in large part because Haaretz’s lack of assets in Ontario would mean that any order made against it would have to be enforced by Israeli courts, thereby raising concerns about a multiplicity of proceedings” (para 142). Similarly, Justice Cote concluded (paras 82-83) that the fact that an Ontario order would have to be enforced in Israel was a factor that “slightly” favoured trial in Israel.
