My opinion would be that it depends on if the dogs are a bother you or someone else. I live across the street from a big park that is attached to a school and three playgrounds. The entire area is an on leash park. This means absolutely nothing to about 90% of the dog owners.
Personally, if I am in my house and so are my kids and no other kids are in the park being bothered, I couldn't care less. If my kids or myself are in the park, or on their way to school, and a dog is running wild it really bothers me. My kids have been chased, jumped on and/or nipped by too many dogs (many big dogs) who apparently are "friendly" or "have never bitten before". This infuriates me. Some dog owners just don't get it. Another excuse is a "If your child didn't run, my dog wouldn't have chased him".
My family loves dogs but we do not appreciate a strange dog charging at us. My kids have nearly had heart attacks from the antics of some of these dogs. One of my son's classmates has a huge scar from a dog running wild in the park and jumping up and biting his lip.
I have in the last few years developed a severe allergy to most dogs so even if they brush up to me, I get a horrible reaction. If I am walking my kids to the school or community centre we have a right, in a on leash park, not to be approached by an off leash dog.
There have been huge problems between neighbours in the past. I have never gotten involved but I will say this. There are about two animal control officers in the City of Toronto that make the rounds. Yes, two. If you have a problem you can call them and someone should eventually investigate. Otherwise, if the issue is more a potentional dangerous or aggravating situation, I would call your local police station at the non emergency number. For instance if you are in 55 Division you would call 416-808-5500. If you are in 54 Division call 416-808-5400, etc.
I hope this helps.
