What is the test for a parent's right to privacy under s. 7 of the Canadian Constitution?

In Blencoe, Bastarache J. refers to Godbout v. Longueuil (City), 1997 CanLII 335 (SCC), [1997] 3 S.C.R. 844, wherein La Forest J., writing for L’Heureux-Dubé J. and McLachlin J. (as she then was), stated, at p. 893: … [T]he autonomy protected by the s. 7 right to liberty encompasses only those matters that can properly be characterized as fundamentally or inherently personal such that, by their very nature, they implicate basic choices going to the core of what it means to enjoy individual dignity and independence. … [P]arental decisions respecting the medical care provided to their children fall within this narrow class of inherently personal matters. In my view, choosing where to establish one’s home is, likewise, a quintessentially private decision going to the very heart of personal or individual autonomy. (emphasis added)
