Hello Carla,

If you just see "Regular" that is for "Regular Parcel".

Example of what you should see:

Canada Post (Priority Courier, 2011-04-12)

Canada Post (Xpresspost, 2011-04-12)

Canada Post (Expedited, 2011-04-12)

Canada Post (Regular, 2011-04-13)

Canada Post (Lettermail: estimated 4-6 business days)

Did you setup your "Lettermail" correctly on Canada Post side? Do you have a link for your website.
