Aragon (Wellesley) Development (Ontario) Corp. v. Piller Investements Ltd. will be useful to the real property bar for its summary of the effect of the Land Titles Act on possessory and prescriptive rights (starting at para. 122), abandonment of easements (starting at para. 154), and prescriptive easements (starting at para. 165).
The Court of Appeal decision in Hunsinger v. Carter contains a statement of the principles of establishing an easement by prescription (which, as I like to point out, is a limitation issue):
(1) Establishment of an easement by prescription
 An easement by prescription can arise either under s. 31 of the Real Property Limitations Act, R.S.O. 1990, c. L.15, or pursuant to the doctrine of lost modern grant. Both have the same four requirements, which were properly recognized by the application judge: i) a dominant tenement that enjoys the benefit of the easement and a servient tenement whose owner suffers some use of its land; ii) the properties cannot be owned by the same person; iii) the benefit of the easement must be reasonably necessary for the enjoyment of the dominant tenement; and iv) there must be 20 or 40 years’ (see: Kaminskas v. Storm, 2009 ONCA 318 (CanLII), 95 O.R. (3d) 387, at paras. 31-36) continuous, uninterrupted, open, and peaceful use enjoyed without obtaining the permission of the servient tenement owner. See: Henderson et al. v. Volk et al. (1982), 1982 CanLII 1744 (ON CA), 35 O.R. (2d) 379 (C.A.).
 After a property has been registered under the Land Titles system, a pre-existing prescriptive easement over the land can be established if the four criteria can be proved to have been met before the land was transferred into Land Titles: Carpenter v. Doull-MacDonald, 2017 ONSC 7560 (CanLII), at paras. 54-55.
