I live in Burlington, 30 minutes west of Toronto, and there is a large number of potential landscape and nature photography locations here. Everything from the industrial cityscapes of Hamilton, the gardens and trails of the Royal Botanical Gardens, the cliffs, ravines, woods, creeks, waterfalls, wildlife, and farms of the Bruce Trail and the Niagara escarpment. If you would like to shoot some great sunrises go west to Mississauga on the shores of Lake Ontario and look back towards Toronto, the sunrise over the CN Tower is fantastic. Don't forget Niagara Falls, one of the natural wonders of the world, only an hour and 15 minutes from downtown Toronto. These combined with the locations mentioned above should keep you shooting away for awile. Have fun, and good luck.
