Those flying on this flight should know that there is a chance that it will leave from the farthest reaches of terminal 1 at Pearson, which means that there is a possibility that they will have to walk to the plane outside. Not a big deal really, and we did it in the middle of January, and it wasn't too cold, though some people might want to look into keeping their jackets with them.
Other than that it was a straightforward flight. We were traveling with a baby but our flight attendant (Chelsea) said to ask her for anything to make it easier. As it was he slept for about 90% of the 2h30m flight. We were happy with the flight.
