The following excerpt is from Boone v. Kyeremanteng, 2020 ONSC 198 (CanLII):
Where the person challenging the constitutionality of a law fails to provide an adequate factual basis upon which to decide the challenge, the challenge fails: Ernst, at para. 22. The lack or absence of the requisite factual basis “is not just a technicality that [can] be overlooked, but rather it is a flaw that is fatal to the [challenging party’s] position”: Mackay v. Manitoba, 1989 CanLII 26 (SCC),  2 S.C.R. 357, at p. 366.
