Usually Dragster is first major attraction, around 25MPH Sustained winds and the Top-Hat. Sky ride is always shut down for even the slightest wind it seems. I would imagine Magnum may have trouble in High Winds next, but I'm sure there are more people here that could answer this question better than I. The wind was rather brisk today and there was not any weather related downtimes.

The CP webste says :
High winds:
Demon Drop, Gemini, Giant Wheel, Magnum XL-200, Mantis, maXair, Mean Streak, Millennium Force, Power Tower, Raptor, Skyhawk, Sky Ride, Space Spiral, Top Thrill Dragster, Snoopy Bounce (in Camp Snoopy), RipCord (in Challenge Park) and Zoom Flume (in Soak City).
That covers a lot of the big rides. I do know that Sky Ride seems to close as soon as the winds pick up even to about 15-20.
