How to use GeoTargetly to change currency only?

Hello!

I am currently trying to use Geo Targetly to redirect Canadian customers to a Canadian version of my online store (we are selling bed frames). So the .com version of the website would be in USD and the .ca version would be in CAD.

Does anyone know the best and cheapest way to do this? Would I have to duplicate the website and change the currency from USD to CAD and connect the .ca domain? Because if I did that I would have to pay for another site plan which I do not want to do. Or is there an easier way to do this by just duplicating the Shop page on the .com site and somehow changing the currency (and giving it a slug that is something like /ca)?

Has anyone else had to deal with this before and if so what was your solution?

Thanks in advance! Any help is appreciated.
