Parking Across the Street on West?

Hi everyone,

I'm a first-year commuter student that drives to school. I usually park at someone's house (I pay monthly for a spot) and then walk ~20 min to either West or main campus.
However, today I noticed an empty "lot" right across from Duncan MacArthur Hall. Of course the parking is paid at Duncan MacArthur, but what about the empty bit across the road? I don't think Queen's owns it, and there was a car parked there with no permit or anything. I often start my day at MacArthur and parking directly across the road would be very beneficial for those days.
Is there somewhere I can find info? Will I get a ticket for putting my car there? Thanks.
