The ontario building code says... 9.14.6.1. surface DrainageYes I understand what you are saying now. But anyone taking the water down from the eve's should not be pointing the water further closer to the property line. Send it forward or back. I've got a long 8ft extension out front which I want to replace with something a bit longer. Out the back it's about 15 ft. This way the water is far enough away from eveything and possible underground trickle back.
(1) The building shall be located or the building site graded so that water will not accumulate at or near the building and will not adversely affect adjacent properties.
If your neighbor's water is flowing onto your property, you can call the building department and they will assess the situation. My experience is they will ask the offender to re-direct water to the front or back of the property whenever possible. If there has been a grade change (usually filling in of a swale), they could order the homeowner to restore the grade.
When they came to my place they had grade maps from 1969 in hand, they asked my neighbor to reconnect downspouts to the underground drain AND restore the swale they filled in on their property. They haven't done the work yet -- the order is 7 years old.
