We're playing darts in the dark until we know where this is happening. While not a structural issue, one municipality I know of wants a permit if plaster is removed. Doors and windows can be changed without a permit if openings stay the same. Some parts of Toronto needed permits to re-asphalt a driveway. Etobicoke doesn't.
Hamilton wanted a survey for a neighbourhood 90 years old. What moved???
In some municipalities a contractor must provide drawings stamped by an engineer or architect for any work, even like-for-like restorations. A homeowner may be exempt from this extra cost if they do the drawings. Could be a couple of thousand dollars.
With this being an exterior wall the security of your home will be compromised during construction. One trick unethical contractors use is to bid cheap and once the wall is down, suddenly find "Hidden damage" that requires a lot more money. Work stops until you agree and alternate contractors will be unwilling to get involved due to potential legal disputes.
