I've been getting conflicting advice about this, and figure if there's a spot that would know the answer one way or the other, it's onstartups.com
In a nutshell I'm trying to find out if I have to register in every province that I wish to acquire business in. For example, if I'm registered in PEI, but wanted to acquire some contracts from customers or companies in Nova Scotia, would I have to register in both provinces to legally acquire business in either jurisdiction? If so, would it be easier to just register as a federal incorporation and be done with it?
