Class Certification in Canada In Canada, class actions may be pursued in either the Federal Court of Canada or in the courts of general jurisdiction of the Provinces The Federal Court of Canada’s jurisdiction is much narrower than that of the United States federal courts The vast majority of class actions are therefore pursued in the Provincial courts of general jurisdiction This sometimes results in two or more Provincial Courts certifying overlapping extraterritorial classes Due to the size of its population and economy, Ontario appears to attract more class actions than any other Province Ontario has an opt-out regime, but some Provinces, such as Alberta, have an opt-in regime
