I've been visited by the city a few times
1 - Because the stone steps walking up to my house were crooked/became off-set
2 - I had soft blue bulbs (no, not xenons) in the front porch light instead of yellow/white ones
3 - The pile of snow accumulated by my snowblower (I put it all in the same area) was too large
4 - My dad parked his boat at the side of our house.... but we're 2 feet within the max of a boat being allowed to be parked on your property. Neighbour complained every month and at one point, the office stopped taking measurements because they kept sending the same guy.
Neighbours are idiots.... but the city still has to investigate any and every claim. PS: No, I didn't change or get ticketed for any of the above.
As I said. Neighbours are idiots.
Before the city can do anything they have to give you in writing the infraction, the solution, the deadline to be changed AND the possible fine. If you don't do any of that, then they will have to go file with the provincial offences court (which they will never do if it is under $500).
Geez... neighbours from hell huh? You need to have a motorcycle party in your street. 100+ bikes revving like crazy and call it "STFU NEIGHBOURS AND MIND YOUR oWN buSiNESS"
