What makes a search reasonable according to the Charter of Rights and Freedoms?

A search is considered reasonable under the Charter of Rights and Freedoms when it is authorized by law and conducted in a reasonable manner. This requirement ensures that individuals' rights to privacy and security are respected. The law must provide a foundation for the search, and the manner in which the search is executed must adhere to principles of fairness and proportionality, being justified under the circumstances.

A search conducted by law enforcement must be based on lawful authority, which often involves a warrant issued by a judge, unless exceptions apply, such as exigent circumstances. The requirement for the search to be conducted reasonably addresses factors like the scope, timing, and methods used during the search, which must not be overly invasive or arbitrary.

In contrast, other options present misunderstandings. For instance, the implication that a search is reasonable solely because it is performed by a police officer disregards the necessity of legal authorization and execution in a reasonable manner. Conducting a search without any warrant or legal basis fundamentally contradicts the essence of what constitutes a lawful search. Lastly, the notion that a search must only occur on public property overlooks the fact that private property can also be entered under certain legal conditions, further emphasizing the need for a lawful framework guiding the search process.
