Le v. British Columbia (Attorney General)

It is notable that the GGPPA does not itself define the word
"stringency" used in ss. 166 and 189. But this does not mean that the
Governor in Council's discretion with respect to listing is "open-ended and
entirely subjective": Alta. C.A. reasons, at para. 221. Rather, the Governor in
Council's discretion is limited both by the statutory purpose of the GGPPA
and by specific guidelines set out in the statute for listing decisions: see
Canada (Minister of Citizenship and Immigration) v. Vavilov, 2019 SCC 65, at
para. 108; Katz Group Canada Inc. v. Ontario (Health and Long-Term Care),
2013 SCC 64, [2013] 3 S.C.R. 810, at para. 24. …. In other words, although
the Governor in Council has considerable discretion with respect to listing,
that discretion is limited, as it must be exercised in accordance with the
purpose for which it was given. The Governor in Council certainly does not,
therefore, have "absolute and untrammelled 'discretion'": Vavilov, at para.
108, quoting Roncarelli v. Duplessis, [1959] S.C.R. 121, at p. 140.
[58] As I read those statements, the test of reasonableness, in the limited sense of
reasonable interpretation of the governing statute, applies equally to all subordinate
legislation. The test is a deferential one that recognizes the governing statute may
be subject to a range of possible reasonable interpretations, but the LGC does not
benefit from any different or broader definition of reasonableness.
[59] That was the approach adopted by the Federal Court of Appeal in Portnov v.
Canada (Attorney General), 2021 FCA 171. The Court said at paras. 19 and 20:
19 There are three parts to the Katz rule: (1) when a party challenges the
validity of regulations, the party bears the burden of proof; (2) to the extent
possible, regulations must be interpreted so that they accord with the
statutory provision that authorizes them; and (3) the party must overcome a
presumption that the regulations are valid. On the third part, Katz suggests
(at paras. 24 and 28) that the presumption is overcome only where the
regulations are "irrelevant", "extraneous" or "completely unrelated" to the
objectives of the governing statute. A leading commentator on Canadian
administrative law calls this "hyperdeferential"…
20 The first two parts of the Katz rule are well-accepted, judge-made
principles. The third part — the presumption and the very narrow ways it can
be rebutted — is more controversial. In my view, later jurisprudence from the
Supreme Court, particularly Vavilov, has overtaken it.
[60] And at para. 27:
27 More fundamentally, Vavilov instructs us to conduct reasonableness
review of all administrative decision-making unless one of three exceptions
leading to correctness review applies. This applies to regulations as a
species of administrative decision-making… For good measure, Vavilov cites
Green and West Fraser with approval — cases that conducted
