A more complete guide to Canadian addressing

Canada's addressing guidelines are different than what Americans are used to. To begin with, everything should be written in capital letters, although this is not required. Next, the apartment number is written at the beginning of the street address line with a hyphen separating it from the building number (e.g., apartment #6 at 111 Somewhere St would be written "6-111 SOMEWHERE ST"). The other difference is that the direction of the street comes at the end of the street line, not between the building number and street name. As for the city/province/postal code line, no commas are to be used. The City and province are to be separated by a single space and the province from the postal code by two spaces.
