 G.J. EPSTEIN J.A.: — The appeal underlying this motion
for security for costs has its genesis in Ecuador. The appellants
(the “Ecuadorian plaintiffs”) hold a judgment of approximately
$9.5 billion from an Ecuadorian court (the “Ecuadorian judgment”) against the respondent, Chevron Corporation.1 The
Ecuadorian plaintiffs seek to enforce that judgment in Ontario
against Chevron and its seventh-level, indirect subsidiary, Chevron Canada.
 Chevron and Chevron Canada initially contested the jurisdiction of Ontario courts to enforce the Ecuadorian judgment.
The matter reached the Supreme Court of Canada, which
affirmed Ontario’s jurisdiction over the Ecuadorian plaintiffs’
action: Chevron Corp v. Yaiguaje,  3 S.C.R. 69, 
S.C.J. No. 42, 2015 SCC 42.
 Following the Supreme Court’s ruling, Chevron and
Chevron Canada brought motions for summary judgment
before the Ontario Superior Court. Both motions sought the
dismissal of the Ecuadorian plaintiffs’ claims against Chevron
Canada, on the basis of its separate corporate personality from
Chevron. The Ecuadorian plaintiffs brought a cross-motion for
summary judgment, seeking a declaration that Chevron Canada’s assets were exigible to satisfy Chevron Corp.’s judgment
debt. The Ecuadorian plaintiffs also brought a motion to add
Chevron Canada Capital Company (“CCCC”) as a defendant to
their action, and to strike the defences in Chevron Corp.’s
statement of defence.
 The motion judge granted the respondents’ motion for
summary judgment. He dismissed the Ecuadorian plaintiffs’
cross-motion and motion to add CCCC as a defendant, and
1 The judgment was originally in the amount of approximately US$18 billion before being reduced to approximately US$9.5 billion by the National
Court of Justice of Ecuador in November 2013.
