Are a virtual office and business domiciliation the same thing?

Almost: domiciliation is the legal function, the one that gives you a registered office with the REQ, while a virtual office refers to a set of services built around that address. At Ancre, the two come together: the civic address at suite 402 serves as the registered office, and the virtual office services come with it, scanned mail, a 514 line from the Siège plan, a conference room, and offices by the hour or the month. Some virtual offices sold online, though, are just an address with no human reception, which can cause problems during a bank verification. Always check that a person actually receives mail at the declared address.
