Can the police force force entry into a person's home to investigate a 911 call?

... [T]he importance of the police duty to protect life warrants and justifies a forced entry into a dwelling in order to ascertain the health and safety of a 911 caller. The public interest in maintaining an effective emergency response system is obvious and significant enough to merit some intrusion on a resident's privacy interest. However, I emphasize that the intrusion must be limited to the protection of life and safety. The police have authority to investigate the 911 call and, in particular, to locate the caller and determine his or her reasons for making the call and provide such assistance as may be required. The police authority for being on private property in response to a 911 call ends there. They do not have further permission to search premises or otherwise intrude on a resident's privacy or property. In [Dedman v. The Queen, 1985 CanLII 41 (SCC), [1985] 2 S.C.R. 2] at p. 35, Le Dain J. stated that the interference with liberty must be necessary for carrying out the police duty and it must be reasonable. A reasonable interference in circumstances such as an unknown trouble call would be to locate the 911 caller in the home. If this can be done without entering the home with force, obviously such a course of action is mandated. Each case will be considered in its own context, keeping in mind all of the surrounding circumstances.
