If you need to be sure your luggage makes it, I wouldn't book it. There's a chance your bags won't make it even if the flight is on time.
Winter departures are delayed during bad weather due to the need to deice the plane before it is cleared to line up for runway departure.
If your YVR PER flight is on QF and the AC YYZ YVR flight is late then there might be a problem unless both flights segments are issues on the same ticket stock (QF or AC).
