Hi Drevni,
I am an expert at this... not finding owls, asking for advice (lol). I have received some great help from the contributors to this forum. If you check some of the olders posts in Toronto Reports or Bird Photo Corner, you'll find some directions in there. The Barred, Great Horned, Saw Whet, Long Eared and Short Eared owls that have been reported over the past few months are generally out past the bridge, though not always. A good bet (without getting way too detailed and confusing) is to check the wooded areas (around peninsula B) on your right a few minutes walk past the bridge. But the best bet is to hook up with one of the friendly and knowledgeable birders that use this forum. I'm sure you will get some more good advice.
Joe
