Background facts

The case involves a dispute between two insurers, Zenith Insurance Company Ltd. and Chubb Insurance Company of Canada, regarding which insurer is responsible for statutory accident benefits following a car accident in Ontario. Ms. Morris, the claimant, was insured under a Zenith policy issued in Alberta for her Lexus. While in Ontario, the Lexus was stolen. She rented a Hyundai, insured by Chubb, and was later involved in an accident while driving it.

She claimed accident benefits from Chubb, who paid the benefits but then initiated a priority dispute, asserting that Zenith, being licensed in Ontario, was responsible under Ontario’s statutory insurance framework.

The arbitrator’s findings

The arbitrator concluded that Ontario's Insurance Act applied to Zenith due to its licensing status in Ontario. Citing section 45(1) of the Act and reciprocal provisions in Alberta's Insurance Act, the arbitrator found that Zenith was obligated to provide Ontario-level statutory accident benefits. He rejected Zenith’s reliance on Travelers v. CAA, finding it distinguishable because that case involved an out-of-province accident.

The legal framework: statutory accident benefits and priority rules

Ontario follows a no-fault statutory accident benefits system under section 268 of the Insurance Act. Section 268(2) provides a priority scheme to determine which insurer pays benefits when more than one policy may apply. If multiple insurers are potentially liable, the regulation ensures timely compensation to claimants while disputes among insurers are resolved separately.

Additionally, section 45(1) of the Insurance Act requires any insurer licensed in Ontario to abide by local insurance obligations for accidents occurring within the province, regardless of the jurisdiction where the policy was issued.

Key issue on appeal: jurisdiction and territorial reach

Zenith argued that the arbitrator exceeded his jurisdiction by effectively applying Ontario law to an Alberta policy, and that this amounted to unconstitutional territorial overreach. It cited Travelers v. CAA, where the Ontario Court of Appeal cautioned against applying Ontario’s Insurance Act to out-of-province accidents merely because the insurer was licensed in Ontario.

The court rejected this argument, emphasizing that unlike Travelers, the accident in this case occurred in Ontario. Therefore, Ontario had jurisdiction both over the insurer (through its license) and the accident. The court held that section 45(1) functions similarly to a PAU by ensuring that insurers licensed in Ontario cannot evade statutory obligations merely because their policies originate in other provinces.

Analysis of reciprocal legislation

While the arbitrator referenced section 33 of Alberta’s Insurance Act, which mirrors Ontario’s section 45(1), the court clarified that this was evidentiary rather than jurisdictional. The true legal authority for the decision was Ontario’s own licensing condition, not Alberta’s legislation. Nonetheless, the existence of reciprocal provisions reinforced the mutual responsibilities between provincial insurance frameworks.

The role of prior case law

The court distinguished Travelers v. CAA on the basis that it dealt with an accident outside Ontario, and reiterated that its constitutional concerns do not arise when the accident occurs within the province. The court further supported its ruling by referencing Healy v. Interboro, which held that insurers who file a PAU—or are otherwise bound by reciprocal licensing terms—must adhere to Ontario’s priority rules when the insured event occurs within Ontario.

Final outcome and costs

The court dismissed Zenith’s appeal, affirming that it must bear responsibility for the accident benefits as the priority insurer. The court ordered Zenith to pay $7,500 in costs to Chubb. The decision reinforces the principle that insurers operating across provincial borders must comply with the regulatory framework of the jurisdiction where an insured event occurs, especially when licensed in that jurisdiction.

Implications of the ruling

This ruling affirms that licensing status in Ontario triggers full participation in the province’s statutory benefits and priority dispute scheme, regardless of where a policy was initially issued. It offers clarity on how Ontario’s insurance laws interact with out-of-province insurers and underscores the binding nature of conditions imposed through licensing, particularly under section 45(1) of the Insurance Act.
