Snow storms are great for students, but bad for travellers.

Hundreds of flights out of Toronto Pearson International Airport are being cancelled or seriously delayed on account of today's snow storm. 

Significant snowfall, ice pellets and high winds in southern Ontario today will affect airport operations, leading to cancellations and delays. If you are travelling, please confirm your flight status with your airline: https://t.co/ZxEmdBHBEF. pic.twitter.com/ieAQ6U7CGB
