That's they way it's usually announced except today at YYZ as the announcement of pre-boarding for seniors or families with young children was made but not emergency exit flyers. I was near the gate area and after some idiot in Zone 2 tried to board the GA scolded a bunch of us nearby so I politely asked about passengers in exit rows and it seemed like she'd forgotten to include that in the announcement and only then realised it. She told me to wait until I was called and then 4 seconds later went to the mic and called for exit row passengers to also board which earned her a free eye roll from me.

Maybe it just wasn't her day as all the other WJ flights called for exit row passengers to join the pre-boarding group and it's really handy with carry-on only.
