In the Greater Toronto Area (GTA) search warrants are being used more and more in investigations of gun possession. Often the search warrants are obtained when police officers are given information from confidential informants (usually citizens). A Justice of the Peace, usually hears the information and decides to grant or deny a search warrant for a particular place. Often, the police attend and find guns and drugs. Even if the search warrant should not have been provided the court may still admit the firearms and illegal drugs found from an illegal search.
Each case depends on its facts, the law, how police conducted their investigation and of course the decision maker. It is important to review all the evidence with your lawyer and provide any information (whether you think it is important or not), to defend your case.
