Annoying Dogs/Neighbours - Condo Rental

[Danny Di]

Hey everyone,

I'm fuming at the moment and need some suggestions.

I own a condo which I plan to lease out either short or long term.  I found the perfect tenant, A++, privately.  As we filled out the paperwork for the lease, my neighbors dogs start going at it...literally for 15-20 mins straight.  The unit next to me has 2 dogs in it which I wasn't aware of and the one next to that has one.  The one next door with the two just bark and yell endlessly.  As he was signing the papers he backed out and basically advised that he can't handle the dogs and noise.  

I don't blame him, even I can't handle it and would never lease a place with such noise around.  I'm literally pissed.

I'm been living in the property since last summer and never heard them.  I did some digging and realized these people just moved in yesterday!! Great luck on my behalf.  They're tenants and signed a 1 year lease agreement.

I'm basically screwed...I can't lease, even sell if I wanted to with these dogs, they're costing me a ton of cash.

I got security to write up a letter to the general manager and office.  My question is, what else can be done, legally? The unit is in Toronto, ON, CAN.

Just want to hear from the pros and veterans on how to handle this, other than the actions I've already taken.

Thanks!
