I live in and do a lot of shooting in NYC. My travel light outfit is a Nikon D5200 (19.5 oz.), Sigma 10-20 f/4-5.6 (18.2 oz.), and Sigma 18-200 Macro OS HSM (15.2 oz.). Altogether that's 3.3 pounds plus the bag, an extra battery, a lens pen, a microfiber cloth, and a few index cards and pencil to take notes.
I didn't get a chance to finish before. My point is that the Canon SL1 along with a lens like the 18-135 IS or an all-in-one is not that heavy and covers most situations you'll encounter in a city. Add an ultrawide like a Sigma 10-20 f/4-5.6, Tokina 11-16 f/2.8, or the lightweight Canon 10-18 and you're covered for just about everything.
I would also bring a good compact for the times that you don't want to carry the DSLR.
