You can't consider yourself a Toronto rider unless you've had a run-in with the streetcar tracks. I think they put them there to remind us how vulnerable we are.
As other say, key thing is to approach them with caution, and at an angle that's as close to perpendicular as possible. It's often better to cross a road in two stages rather than trying to make a left where there are tracks -- go straight across an intersection and then go straight across the road, riding or pushing, whichever is safer. I have a left on Gerard or on Dundas after the Don Valley bridge, and I keep thinking one day those tracks are going to jump out and grab me. If there's no traffic at all, I cut across all four lines at the sharpest angle I can, but if there's traffic I stop, wait for a gap and then ride straight across the road, crossing all four lines at a perfect right angle. Well, ok, sometimes it's 70 or 80 degrees.
Also for 14 miles, bring water in this heat.
