I'm pretty sure I've done fixture work for them at some point in the past. The name sounds very familiar. We often work for their customers, but sometimes deal with the die shops directly. Just checked and we last did some repair work for them in 2018.
I know the auto industry is changing, and sometimes bigger/older places are slow to implement change that would help them innovate/renovate to stay alive stave off overseas competition. I also know 40 years is a long time, and there had to be a handoff of ownership/leadership at some point along the way, and that often never goes as plan. Real estate prices is a another big kicker in the gta, and a possible source of failure there a few different ways depending on how leveraged they are. Could also have been the original owner/founder decided to pack it in and didn't have a buyer. Who knows.
I'm always curious about how and why business' like this fail. I love analyzing the failures of everything, and fortunately/unfortunately have rode with a few companies into the ground over the past 20 years.
