International Commercial Arbitration Act (ICAA), UNCITRAL Model Law, institutional arbitration (ICC/LCIA/ICDR/SIAC), seat of arbitration, enforcement of foreign awards under the New York Convention, and drafting arbitration clauses.
Ontario is a Model Law jurisdiction. The International Commercial Arbitration Act, 2017 (ICAA) incorporates the UNCITRAL Model Law on International Commercial Arbitration (as revised in 2006) and the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (New York Convention, 1958). Ontario courts have consistently demonstrated a strong pro-arbitration stance, refusing to intervene in arbitral proceedings and enforcing awards on a summary basis.
Toronto is increasingly used as a seat of arbitration for North American commercial disputes — benefitting from Toronto's neutrality between US and international parties, its sophisticated commercial courts (Commercial List of the Ontario Superior Court of Justice), and its position in a Model Law jurisdiction.

Canada is a party to the New York Convention (1958). The ICAA implements the Convention in Ontario. To enforce a foreign award:
Public policy: Ontario courts interpret the public policy exception narrowly. Only awards that are fundamentally offensive to the basic principles of justice — not merely incorrect or contrary to Ontario law — will be refused enforcement on public policy grounds. Ontario courts have enforced awards from many civil law jurisdictions (China, Russia, UAE) on this basis.
A well-drafted arbitration clause is essential — ambiguous or pathological clauses generate satellite litigation on scope and procedure before the arbitration can proceed. Essential elements:
Sample ICC clause (Toronto seat):
"Any dispute, controversy or claim arising out of or relating to this contract, or the breach, termination or invalidity thereof, shall be settled by arbitration in accordance with the ICC Rules of Arbitration. The seat of arbitration shall be Toronto, Ontario, Canada. The arbitral tribunal shall consist of [one/three] arbitrator[s]. The language of the arbitration shall be English. This arbitration agreement shall be governed by the laws of the Province of Ontario and the laws of Canada applicable therein."
International commercial arbitration in Ontario is governed by the International Commercial Arbitration Act, 2017 (Ontario), which incorporates the UNCITRAL Model Law on International Commercial Arbitration (2006 version). Domestic (non-international) commercial arbitration is governed by the Arbitration Act, 1991 (Ontario). The distinction turns primarily on whether the parties have their place of business in different states at the time of the arbitration agreement.
Foreign arbitral awards from New York Convention countries are enforced in Ontario under the International Commercial Arbitration Act, 2017. The award creditor files a court application in the Ontario Superior Court with the original award and arbitration agreement (or certified copies). The court grants recognition and enforcement unless the respondent proves a ground to refuse (limited grounds under Art. 36 / NY Convention Art. V). Once recognized, the award is enforceable as an Ontario court judgment.
A well-drafted international arbitration clause should specify: the arbitral institution (ICC, LCIA, ICDR, SIAC, or ad hoc); the seat (legal place) of arbitration; the language; the number of arbitrators; the governing law of the arbitration agreement; and any carve-outs from arbitration. The seat determines which national courts have supervisory jurisdiction over the arbitration.
Under the ICAA (Article 34 of the Model Law), an award can be set aside only on limited grounds: invalid arbitration agreement; no proper notice; award outside scope of submission; improper tribunal composition; subject matter not arbitrable; or award conflicts with Ontario public policy. The 3-month limitation period from receipt of the award applies to set-aside applications.
