5.21 Addresses

Street and avenue designations up to and including Tenth are usually spelled out, especially when this helps to prevent confusion with the building number. If the street name is written in numerals, modern usage tends to favour cardinal rather than ordinal numbers:

  • 9511 Tenth Avenue
  • 96 Ave.
  • 101 St.

In abbreviated form, apartment or suite numbers are written before the building number and are often followed by an en dash:

  • 107–6807 92 Ave. N.

Identify floors of a building as follows:

  • 11th floor, L’Esplanade Laurier
