Just wondering if anyone had any insight on using a service such as this?

We're looking at starting up another warehouse location on the other side of Canada to better serve our customers on that end of things and I've been looking for companies that do this sort of thing. We're not ready to open up a completely new office/warehouse, but using a company that strictly warehouses and ships from a remote location.

Has anyone done this before easily?

What are some of the drawbacks and problems running things this way?

Does anyone know of any companies that do this in or around Ontario, Canada or Quebec, Canada?
