There is a priority lane at YOW. I was speaking to a concierge agent yesterday; she says that it has been open for 2 months, or so.
It is not open at at times of the day - it is open for 2 periods - one in the morning, and one in the afternoon to early evening (I can not remember the times she said the priority lane is open).
This may, for those SE/E or those flying business class, perhaps help during the times when the security line is normally otherwise very long (see link to other thread for details:

PS-I wonder if AMEX platinum cardholders can use this lane, just like the one at YYZ.
