That's actually entrenched in the documentation.
I am reading from another regulation that was passed. This is SOR/2022-21, which says at 4(2) that, “A person must not cause a person under the age of eighteen years to travel to or within 500 metres of an area where an assembly referred to [as an unlawful assembly] is taking place.”
That kind of language, if enforced, actually facilitates your policing and the safe removal of the child.
