@Ralph R. no offence here.

In addition, I'm going to put up a small section of fence that should solve the issue of the neighbor trying to use the yard for their dog.For anyone curious.

Which means that an employee could argue that his employer can not fire him because he did not enforce his contractual right to terminate him the last time he committed a fireable offence.

i'd do it. i allow pets and they all want fenced yard.but they have to pull a permit and still talk to the "installer" to make sure he knows what he is talking about. so easy to read these guys just by talking to them.... how far in the ground, what's the span, height of fence, cone or straight hole, etc, etc..again, not without a permit.

Meanwhile, you should carefully study this chilling document, "Offences Under the Residential Tenancies Act, 2006" and make sure you don't commit any. http://www.mah.gov.on.ca/Page1175.aspx

Because I can find one for alcohol.No offence intended, but there's no way to argue that one should be legal and not the other.

They installed a fabulous fence too.My tenants loved the house, by the time of fence installation they had lived there for years, and they wanted to have privacy. 

There are too many complications (when things lke this happen) when the fence straddles the property line. 70 feet of fence failing sounds like a huge windstorm or vandelism or rot or someone ran into it with a ATV while they were doing donuts in the back yard.I'd hire someone from Lyft or fiverr.com to drive over and do a Facetime with you so you can get a feel of what is actually going on.

There is a lot of face involved in knowing that you have paid the bills and then progressively asking for greater and greater evidence of offences that they know they have committed.

Regarding my dog, I did everything I could do to try and prevent this from happening again, repaired my side of fence, repaired the neighbors side of his fence and haven't received money from him and his fence was never broken, but instead they are hanging by a thread due to water rot on all the boards.
