A worrying winter storm is already causing havoc around Toronto as the city prepares for hazardous travel conditions, airport mayhem, and even freak 30-foot waves on the eve of the Christmas holiday weekend.

Several events are already curtailing activity or shutting down altogether as the storm approaches the city, throwing a wrench into holiday plans for many.

WinterFest at Canada's Wonderland

Wonderland announced on Wednesday that, "Due to inclement weather, the park will be closed on Thursday, Dec. 22," and that "tickets for this date will be valid for any other WinterFest operating date through to Dec. 31."
