I lived in 11 Walmer Rd -- which is owned by the same company -- for 15 years. Our balcony renos started in May of 2018 and we didn't get access to our balcony back until June of 2019. Got to enjoy it for about 3 months before we received our N13 notice saying interior renos (which they told us would be the hallway, lobby, and laundry) would take 3 years and we had to vacate.
Salford is a horrible, horrible company. Throughout the entire process of our 'renoviction' they were constantly rude to us whenever we interacted with them, reminding us they had the law on their side and we shouldn't bother trying to fight it. I fear for the residents of 666 Spadina.
