The major postal system in Canada is known as Canada Post or Postes Canada. There are some distinctions between this mail service and the postal systems in the United States and the United Kingdom.
How to Address Envelopes to Canada is covered in this article
The recipient's name should be printed. Make sure to allow plenty of room above and below the name on the centre front area of the envelope. Mr. or Mrs. are acceptable honorific titles, although they are not needed.
All addresses should be written in capital or block letters, according to postal services.
Any more address lines should be printed below. To guarantee that the letter reaches the correct recipient, you may wish to print the hotel, business, or department name.
On the next line, write the apartment number and street address. Put the apartment or unit number first, then a hyphen, and then the street address. 2-234 Fine St. N, for example.
Punctuation should not be used in Canadian addresses. Because many addresses are scanned by sorting machines, it is critical to write addresses accurately. It will arrive at the destination faster if it is addressed legibly according to Canada's postal rules.
Locate the proper postal and provincial codes. Distinct areas of Canada have different postal and provincial codes for addresses. You must first determine the particular codes, including the right abbreviation of the provinces, before writing out the address.
If the person you're writing to hasn't already provided this information, go to the USPS website or the Canada Post website to find out.
On the next line, write the city, province, and postal code. Make sure they're written in the correct sequence, with two spaces between the province and the postal code.
In the last line, write Canada. Unless you are currently sending mail from Canada, in which case this line is not required, the country name should always be the final line of the address.

Put your return address here. The return address is required so that the receiver knows to whom to send their reply. Make sure the address is legible.
Use the same format to write your return address. The only difference is where you write it; make sure it's in the upper left corner of your envelope. You may also put it in the centre of the envelope's back flap.
When writing an American address, avoid using periods or commas for abbreviations. Use the two-letter state abbreviation. Underneath the last line, which lists your city, state, and zip code, write USA.
If you're writing an overseas address from anywhere other than the United States, include the complete name of the country.
