Decaen v. Decaen, 2013 ONCA 218 deals with parental mobility and restates the test from Gordon v. Goertz,  2 S.C.R. 27:
(b) Gordon v. Goertz
 In Gordon v. Goertz, Justice McLachlin (as she then was), writing for the majority, identified a number of factors relevant to a child’s best interests in the context of possible relocation: (a) the existing custody arrangement and relationship between the child and the custodial parent; (b) the existing access arrangement and the relationship between the child and the access parent; (c) the desirability of maximizing contact between the child and both parents; (d) the views of the child; (e) the custodial parent’s reason for moving, only in the exceptional case where it is relevant to that parent’s ability to meet the needs of the child; (f) disruption to the child of a change in custody; and (g) disruption to the child consequent on removal from family, schools, and the community he or she has come to know.
 At para. 50 of Gordon v. Goertz, McLachlin J. stated that, “[i]n the end, the importance of the child remaining with the parent to whose custody it has become accustomed in the new location must be weighed against the continuance of full contact with the child’s access parent, its extended family and its community.”
