Why let being further than 5 meters from the fence stop the cops from exercising their new powers?

This search was done at Allen Gardens Park in Toronto, much further than 5 meters from the fence line. I actually accidentally witnessed it as I was coming out of an appointment across the street. Because I was across the street I didn't hear the particulars of the incident until I saw the video, though.
