“Paragraph 22(1)(b) of the CLRA provides that an Ontario court may assume jurisdiction if six criteria are met:
22 (1) A court shall only exercise its jurisdiction to make an order for custody of or access to a child where,
(b) although the child is not habitually resident in Ontario, the court is satisfied,
(I) that the child is physically present in Ontario at the commencement of the application for the order,
(II) that substantial evidence concerning the best interests of the child is available in Ontario,
(III) that no application for custody of or access to the child is pending before an extra-provincial tribunal in another place where the child is habitually resident,
(IV) that no extra-provincial order in respect of custody of or access to the child has been recognized by a court in Ontario,
(V) that the child has a real and substantial connection with Ontario, and
(VI) that, on the balance of convenience, it is appropriate for jurisdiction to be exercised in Ontario. [Emphasis added.]
As this court said in Wang v. Lin, 2013 ONCA 33, 358 DLR (4th) 452, s. 22(1)(b) must be read conjunctively. An Ontario court can only exercise jurisdiction under this provision if all six of the enumerated criteria are met.

Section 23 provides:
Despite sections 22 and 41, a court may exercise its jurisdiction to make or to vary an order in respect of the custody of or access to a child where,
(a) the child is physically present in Ontario; and
(b) the court is satisfied that the child would, on the balance of probabilities, suffer serious harm if,
(i) the child remains in the custody of the person legally entitled to custody of the child,
(ii) the child is returned to the custody of the person legally entitled to custody of the child, or
(iii) the child is removed from Ontario.
Because the Ojeikeres’ three children are physically present in Ontario, under s. 23(b) an Ontario court can exercise jurisdiction over their custody or access if satisfied that the children would, on a balance of probabilities, suffer “serious harm” if they were sent back to Nigeria.
Justice Weiler commented on s. 23 in her reasons in H.E. v. M.M., 2015 ONCA 813, 393 DLR (4th) 267. Because the provision is triggered when a child is physically present in Ontario even if the child has been wrongfully brought to this province, s. 23 can override s. 22. Section 22’s aim of discouraging child abduction becomes secondary to s. 23’s aim of preventing serious harm to the child. As Weiler J.A. wrote at para. 87: “[W]hen there is a risk of serious harm to the child, the aim of discouraging child abduction must yield to another purpose of the CLRA, namely, the best interests of the child.”
Section 23 of the CLRA is discretionary. Under s. 25, a court with jurisdiction over custody or access may decline to exercise its jurisdiction where it is of the opinion that another jurisdiction is more appropriate. Although s. 25 could potentially qualify the court’s discretion under s. 23, I find it hard to conceive that an Ontario court would decline jurisdiction under s. 23 if satisfied a child would suffer serious harm if removed from the province.”
