Class Actions Have Become More Common in Canada in Recent

Class actions have become more common in Canada in recent years. That increase in popularity can be explained, at least in part, by the fact that

A) the rules governing class actions are now contained in statutes in every province.
B) liability in a class action can never be appealed.
C) lawyers conducting class actions must work on a contingency fee basis, with the result that their clients are liable for their expenses only if the case is won.
D) they save society money by eliminating the need for similar actions to be brought to court separately.
E) the Supreme Court of Canada recently said that, in contrast to the past, class actions can now be certified even if success for one claimant does not necessarily mean that all of the other claimants will also enjoy success.
