On November 6, 2009, Ontario issued a Notice of Measure claiming that material differences exist in respect of the practice of public accounting in Canada and to protect consumers out of province public accountants would be assessed against Ontario's requirements. Manitoba supported by Alberta, British Columbia and Saskatchewan objected on the grounds that the Ontario regime causes injury to CGAs and impairs internal trade. A Panel convened under the Agreement on Internal Trade reviewed submissions and held a public hearing in Toronto on November 29, 2011. The Panel found that Ontario's notice of measure has impaired or would impair internal trade and has caused or would cause injury. The Panel recommended that Ontario comply with its AIT obligations by April 15, 2012. The outcome is important for CGAs because it removes the last barrier to mobility, allowing CGAs to practice anywhere in Canada.
