I was mainly referring to the ICI sector. Big projects.
Fair enough. There might be a lot of them coming down the pike in the next few years in Ontario and elsewhere (I know Biden got that massive infrastructure bill passed earlier this year).
I recall hearing that some businesses that thrived during the Great Depression included things like small candy companies. Wrigley gum, Mars bars and what not. They were not super expensive at the time, and everyone could enjoy something like that once in a while.
As for what is a truly recession proof business? Funeral homes for sure, barbers/hair stylists. The medical profession in Canada (with the exception of dentists. I mean, if you don't have a job you probably won't go for your cleanings until something goes horribly wrong). Repo/debt collecting probably would thrive in that scenario...
I'm not sure about sex work. I mean, strip clubs are dying across the GTA, so that might be a hard business to remain in.
