Canadian postal codes involve 3 component parts. First is the postal district, which is indicated by a single letter. Each province in Canada has its own postal district. After that is the forwarding sortation area that includes the postal district abbreviation (Example: K1A). There's a space, then a digit-letter-digit code for the local delivery unit (Example: 0B1).
A complete Canadian postal code will be six figures, appearing like this: K1A 0B1.
