I've never heard about this.

What if you want to change your building’s number?
Some numbers have deep significance in certain cultures, which can impact the resale value of a property. As a result, sometimes an owner will seek to change a building’s number.
In Calgary, you must pay $735 to the city for one address number change. If you are changing multiple addresses, the charge is a $735 base fee and then $86 per additional address.
In Vancouver, like other cities, you must be the registered property owner to request a number change. The cost is $690.
In Montréal, you don’t have the option of changing your number. Because numbers are assigned according to where your door is located in relation to the other doors on the street, changing one would mean changing all of them. The exception would be a building with a wide façade, such as an office building. In a case where a door position moves significantly, or a new one is added, a number can be assigned, which costs $56.50 plus taxes. If a number is removed in this case, it cannot be used again. It exists and will be attached to that building, whether it is used or not.
In Toronto, if the owner of a property wishes to change the address of a building, they have to pay $300, and then $29 for each additional address.
