What is the current state of the law in Canada regarding ice hazards?

In saying this, I recognize that we live in a relatively northern climate and that our winter weather conditions often create an environment that is inherently precarious. In Brown v. British Columbia (Minister of Transportation and Highways), 1994 CanLII 121 (SCC), [1994] 1 S.C.R. 420 at p. 439, the court said “Ice is a natural hazard of Canadian winters. It can form quickly and unexpectedly. Although it is an expected hazard it is one that can never be completely prevented.”
