Are you looking for Canadian ETFs or possibly looking to venture into the US?
If you're looking here in Canada, we have a very limited amount of options but options that get you exposure nonetheless. If you're looking on that side of things, you are pretty much limited to one fund manager, that being Global X. They run funds like RBOT, which is their Robotics ETF and CHPS, which is their semiconductor ETF.
Keep in mind, they also have HBGD, which can give you exposure to the data center/infrastructure side of things.
