Section 529.4 — Criminal Code: Omitting announcement before entry

A judge or justice who authorizes a peace officer to enter a dwelling-house under section 529 or 529.1, or any other judge or justice, may authorize the peace officer to enter the dwelling-house without prior announcement if the judge or justice is satisfied by information on oath that there are reasonable grounds to believe that prior announcement of the entry would expose the peace officer or any other person to imminent bodily harm or death; or result in the imminent loss or imminent destruction of evidence relating to the commission of an indictable offence. An authorization under this section is subject to the condition that the peace officer may not enter the dwelling-house without prior announcement despite being authorized to do so unless the peace officer has, immediately before entering the dwelling-house, reasonable grounds to suspect that prior announcement of the entry would expose the peace officer or any other person to imminent bodily harm or death; or reasonable grounds to believe that prior announcement of the entry would result in the imminent loss or imminent destruction of evidence relating to the commission of an indictable offence. A peace officer who enters a dwelling-house without a warrant under section 529.3 may not enter the dwelling-house without prior announcement unless the peace officer has, immediately before entering the dwelling-house, reasonable grounds to suspect that prior announcement of the entry would expose the peace officer or any other person to imminent bodily harm or death; or reasonable grounds to believe that prior announcement of the entry would result in the imminent loss or imminent destruction of evidence relating to the commission of an indictable offence.
