$75M? Get real! That's >2X the project costs. This would set a really bad precedent.
There is no way that the business owners are facing these types of losses. I remember seeing an article in 2023 where the owner of the Apt22 consignment store claimed they had lost hundreds of thousands of dollars in revenue, and ultimately closed down. In the same article K-Thi, the Vietnamese restaurant claimed to have lost $50,000/month in revenue. I guess that now that it's in front of the courts, they will have to prove it.
I don't disagree that construction could have been managed/scheduled better, but part of that was the City trying to appease the business owners.
I'm not unsympathetic to these business owners, but the reality is that some of the pain they are dealing with is self-inflicted. Silver Sage and Diner Deluxe are the primary plaintiffs. I'm a patron of both. I find Silver Sage overpriced and Diner Deluxe poorly managed (I find the service slow). Also, I'm pretty sure Diner Deluxe moved in well after it was known that the City would be undertaking the Main Streets construction in the neighbourhood.
As some of mentioned, some businesses have thrived, despite the construction, while others have failed. I have a hard time believing that those that failed, only failed because of construction.
