This may sound like a silly question, but it is that has been puzzling me. Just keep in mind that I did not grow up in Canada, I grew up in the tropics, and also where I grew up we didn't have a school bus system. You got dropped to school. So today in our area all school buses, both morning and afternoon are cancelled due to the impending freezing rain but school remain open. (it's absolutely bone dry here at the moment). Why do they cancel school buses but still make parents take their kids to school? If the weather is so bad and buses can't run, why do they make parents drive their kids to school? Is it a liability issue? Also if a parent can't drop their kid off or doesn't want to drive in bad weather does this mean a kid gets an unexcused absence?
