I lived right at Yonge & Bloor in the 80's & 90's, I trained my dogs to pee down the sewer grates right outside the front door on Bloor St. and go #2 right at the curb on the sidewalk. My current dog urinates on grass, because there's lots where I live now but I trained her to also go #2 just off the curb on the road (side streets) - doing this on concrete or asphalt allows me to pick up 100% as opposed to struggling to pick up "most" of it in the grass. As for parks around there, well DA, I knew that there were no nearby parks before I got my first dog. There's a small parkette on Park Road at Asquith St but it's pretty useless for dogs. If there are no offleash parks, walk the dog! Walking an hour or two (or more) a day (depending on the energy level of the dog breed) while getting sun, mental stimulation and socialization is the best thing one can do for themselves, and their dog. If someone who lives in a multi-unit building wants a dog and expects to simply toss the pet into a dog park for an hour twice a day, every day, or mistakenly allow them to run wild in neighbourhood parks, then they might want to consider getting a cat instead.
