How have sections 6 and 7 of the Charter of Canada been interpreted?

The petitioner relies heavily on Mia v. Med. Services Comm. of B.C., supra, where these statements appear [p. 291]: … each section and subsection [of the Charter] should be regarded as complementary, assisting and explaining each other, and not in isolation as some writers have suggested. This is particularly so for ss. 6 and 7 as mobility and liberty, particularly in connection with employment, are more than just close neighbours in the constitutional house’. … the gaining of a specific livelihood such as by the practice of a profession … and the liberty of a citizen in connection with … the practice of her profession … Those statements clearly imply that a guarantee of economic rights, at the least the right to practise one’s profession or trade, is contained in the words “liberty of the person” which appear in s. 7.
