Photographing and filming police officers in Canada

Here's an excellent passage from The Canadian Privacy Law Blog:

Full Post

• There is no law in Canada that prevents a member of the public from taking photographs or video in a public place (other than some limitations related to sensitive defense installations);
• There is no law in Canada that prevents a member of the public from taking photographs or video of a police officer executing his or her duties in public or in a location lawfully controlled by the photographer (in fact, police officers have no privacy rights in public when executing their duties);
• Preventing a person from taking photos or video is a prima facie infrigement of a person's Charter rights;
• You cannot interfere with a police officer's lawful execution of his or her duties, but taking photos or videos does not, in and of itself, constitute interference;
• A police officer cannot take your phone or camera simply for recording him or her, as long as you were not obstructing;
• These privileges are not reserved to media -- everyone has these rights;
• A police officer cannot make you unlock your phone to show him or her your images; and
• A police officer cannot make you delete any photos.
