Heard on the radio that YYZ was going to change carry on restrictions back to allowing just a single carry one but no limit on what it is for flights to USA. So rollerboards for laptops would be accepted again. Does anybody know if this is true or not, I called the airport and they have not heard that information. Suppose to be a big announcement at 3pm today on airport security. Have to fly out tomorrow and would change my packing depending on these changes.
