Not sure about the Barrie area, but the city owns a certain footage from the centre of the street, back to tour property ie the boulevard, where I am I believe its 33ft from the centre of the street, they are responsible for that area, past that its your responsibility. I have had issues with plugged drains etc, and they resleeved the area, as the old cast pipes rust and catch every things that passes by it. They covered it, and no increase on taxes or bills etc. Check the city of Barrie, and what they are responsible for, also check the public works dept, and tell them your issues and they might come and run the cutters down your drain for you.
