The mother and two children travelled from Greece to Ontario for a vacation.
The mother subsequently decided to remain in Ontario and commenced a custody application.
The father brought an application under the Hague Convention for the return of the children to Greece, their habitual residence.
The mother argued that the father had consented to or acquiesced in the children's retention in Ontario under Article 13(a) of the Hague Convention.
The applications judge found that the father had not consented or acquiesced, and ordered the children returned to Greece.
The Court of Appeal dismissed the mother's appeal, affirming that acquiescence requires clear and cogent evidence of unequivocal subjective consent, which was not established on the facts.
