I went to several business closing auctions, and one private sale over the past year, and in almost every case it was not the business declines, but rather the owner of the business was made an offer they couldn't refuse. Most were the property value skyrocketed and developers waltzed in flashing multi-million dollar cash deals. One commercial property in Cambridge for instance that was on main drag and bordered residential area ended up selling so property could be converted to two high-rise condo buildings.
Another off the QEW near grimsby sold out when he too was offered huge amount for the commercial property. One more closed because they couldn't renew the lease when the landlord doubled the rate... because Toronto. I guess that was economic decision in part, older owner, wayyy too expensive to move just to work a few more years...
I know another shop owner in Cambridge plans to sell out and auction everything in about 18 months time. He has a small cylindrical grinder I really want... so I look forward to that auction. He owns the industrial condominium he is in too. It has appreciated in value massively... so much so if it was my biz I'd have sold long ago, and moved to rural property with my best machines.
