"As an aside, I have never seen a preferred runway system which stays in place at more than 15 knots crosswind, when a more into wind runway is available (and the usual standard is 10 knots). I am rather shocked that such a situation has been allowed to occur".
In Toronto it's my understanding that operations will stay on the east/west runways unless the steady state crosswind exceeds 25 knots or someone complains. Makes for some interesting arrivals.
