What is the test for a search warrant and a tracking warrant?

In the case of the Search Warrant the test is higher than the reasonable suspicion required for the Tracking Warrant. Citizens have a right to privacy which may not be violated by the police on the basis of suspicion, even if that suspicion is a “reasonable” one. The police must have more than a reasonable suspicion. It was put this way in Hunter v. Southam, 1984 CanLII 33 (SCC), [1984] 2 S.C.R. 145 at p. 167: “The state’s interest in detecting and preventing crime begins to prevail over the individual’s interest in being left alone at the point where credibly based probability replaces suspicion.” [emphasis added]
