Might be good for fellow Ontarians/Québécois. I've been looking for good fares to bring some family over for a visit, and came across this today on ITA Matrix.

Plugged in 7 days round trip from YOW, Feb 3rd, 2015. Got Delta for $718 via DTW and SEA. This amazed me as it's usually quite a bit more coming from YOW.
