Meisels v. Lawyers Professional Indemnity Company, 2015 ONCA 406:
 An order that does not finally dispose of the rights of the parties to the litigation will be a final order for purposes of an appeal if it disposes of an issue that "deprive[s] the defendant of a substantive right which could be determinative of the entire action": Ball v. Donais (1993), 13 O.R. (3d) 322 (Ont. C.A.), at p. 324.
