Yes, here in Canada, they're called CSA "Green Patch Boots" sometimes called "Steel-toe/Steel-shank (or sole)" and are required in a vast array of jobs, from warehousing to construction and includes treework. Really any job where you could drop something on your toe or step on something sharp.
They needn't be steel-toe/shank, new plastic materials pass the impact and puncture tests well enough to get the CSA green triangle and are commonly found in winter work boots.
Since they are required to gain access to any large constuction site, there are CSA green patch brogues and penny-loafers for the engineers and other assorted desk jockeys who occasionally come on site to oversee and want something that goes with their belt and tie.
You can get CSA green patch white nurse's wedges and green patch hi or lo ankle running shoes and green patch hikers. Oh yeah, green patch cowboy boots are popular with truckers.
Having said all that, you can go on any house building site and find small outfit subcontracting carpenters, drywall boarders, etc not wearing what they ought to be, but if they were to have a foot injury, they'd be out of luck for Workman's comp.
Since they're all I've worn to work for a couple of decades, I'd feel odd without them on, and don't find they compromise my climbing at all. I wonder what it would be like to kick a big stack of branches into an armload without them.
Many of us in the trees have a couple or even several pairs, a set for big spurring jobs (Usually Vibergs here in B.C. but Wesco's, White's or Goodhue's in Ontario) a lighter pair for spurless, an insulated pair for winter spurless and right where I am a rubber vamped pair for the rainy season. (I don't care how well you waterproof them, no non-rubber boot stays dry in 4" deep puddles).
