What is the law relating to the duties of motorists as they approach uncontrolled intersections?

The law relating to the duties of motorists as they approach uncontrolled intersections was set out in the seminal case of Walker v. Brownlee, 1952 CanLII 328 (SCC), [1952] 2 D.L.R. 450 (S.C.C.) [Brownlee]. The following observations of Mr. Justice Cartwright, at 461, are apposite to the case at bar: While the decision of every motor vehicle collision case must depend on its particular facts, I am of the opinion that when A, the driver in the servient position, proceeds through an intersection in complete disregard of his statutory duty to yield the right-of-way and a collision results, if he seeks to cast any portion of the blame upon B, the driver having the right-of-way, A must establish that after B became aware, or by the exercise of reasonable care should have become aware, of A’s disregard of the law B had in fact sufficient opportunity to avoid the accident of which a reasonably careful and skilful driver would have availed himself; and I do not think that in such circumstances any doubts should be resolved in favour of A, whose unlawful conduct was fons et origo mali.
