I am just listening to current midnight zulu ATIS and for the first time that I've known from the local FSS, there is a notam advising pilots of 'Flow control' back into Toronto Pearson. When I used to reside in North Bay, that was always included during ATIS updates and sometimes, unless my memory serves me incorrect, during wide open VFR weather, the FSS guys would issue a 'special' simply advising air traffic about Flow back to T.O. Does your airport's ATIS do this routinely?
