Can Instances Be Used As a Service Which Operates Directly From The Target Country?

When I am using an instance for a region like Canada, when I try to use a specific application like Kijiji they easily detect my network and end their service. It is the same for Paypal for example also.

When I am not in a specific country is there a way that I can use instances so my source of the network is not flagged and I can access some apps like PayPal or other payment providers for operating my business?

Thanks. Onder A.
