What is the impact of s. 15(1) of the Charter on Canadian law?

Ten years later, in Law v. Canada (Minister of Employment and Immigration), 1999 CanLII 675 (SCC), [1999] 1 S.C.R. 497, Iacobucci J. spoke of an almost inherent difficulty in the interpretation of s. 15 of the Charter. He stated that “[t]he quest for equality expresses some of humanity’s highest ideals and aspirations, which are by their nature abstract and subject to differing articulations. The challenge for the judiciary in interpreting and applying s. 15(1) of the Charter is to transform these ideals and aspirations into practice in a manner which is meaningful to Canadians and which accords with the purpose of the provision” (para. 2).
