Ontario has enacted and brought into force the International Commercial Arbitration Act, 2017, SO 2017, c 2, Sched 5 (available here) to replace its previous statute on international commercial arbitration. The central feature of the new statute is that it provides that BOTH the 1958 New York Convention and the 1985 Model Law have the force of law in Ontario. Previously, when Ontario had given the Model Law the force of law in Ontario it had repealed its statute that had given the New York Convention the force of law in Ontario. This made Ontario an outlier within Canada since the New York Convention has the force of law in all other provinces (as does the Model Law).
The previous statute did not address the issue of the limitation period for enforcing a foreign award. The new statute addresses this in section 10, adopting a general 10 year period from the date of the award (subject to some exceptions). Section 8 deals with the consolidation of arbitrations and section 11 deals with appeals from arbitral decisions on jurisdiction.
