I don't even think they would cancel the school with the buses down, you must have gone to a different UBC. lol
Reading their policy online, they won't close the campus unless its major before 6am, that's a really big snow fall early to stop the buses. And if it snows bad during the day they'll just inform the profs to leave, signaling school is closed, but if that's the case and the buses are down, people are stranded. lol
This came up during finals, a bunch of people were late due to the snow. The profs were like haha can't help you, UBC is still open. Even though the buses died right after finals ended.
