Most of the Canadian ATC rules are based on US ones , although I am not sure in this particular case it they are exactly the same .Someone from Canada can confirm or infirm that.
US rules require the preceding aircraft be at least 6,000 ft.
and airborne if either aircraft is Category III . Lesser distances for Category I and II aircraft.
