Yes! A major steel supplier to the auto industry, Great Lakes Steel, that used to be in Ecorse and Zug Island are long gone too. I worded there in the early 1960s as a time study analyst but saw the end coming when management folded to the USW by giving them the moon to prevent a strike.
I remember a lot of the steel mills in the USA (and a few in Canada) were in trouble because they never modernized. The industry in Hamilton, Ontario is still strong but they do it with fewer workers; the only way to compete with cheap overseas labour is to use less labour.
