No, that’s not how things work.
For one, there is no such thing as ‘doing work online’. The amount of work it takes to create a construction set of drawings is the same whether your in Australia, Brazil, or China. It’s not like ‘the internet’ eliminates a few sections for you.
Secondly, local designers usually end up saving you money because of their experience in a community. An American might think they can come and design something in Canada - and then realize they need to use the metric system. Then they need to develop a whole new set of drawing standards. And then they need to learn the municipal, provincial, and national building codes. And then they need to learn the green building requirements. And while someone from the states might think the zoning code is set in stone, a local architect would have a relationship with the local political system and know what sort of exceptions a particular project is likely to get. A local architect also knows exactly how to design for the local climate. A non-local architect is going to waste huge sums of money simply getting up to speed.
Thirdly - there is no substitute for an architect being on site during construction. A civil engineer is not trained to put buildings together, and is not trained to see the quality control problems that occur during building construction.
Lastly - most localities have architects that specialize in a wide range of project types. Unless your in the Arctic - it’s a pretty easy job to track down an architect for your building type. And we are talking about an office after-all.
