Certain terms apply. Please speak with Canada Post or your mailing supplier.
It is possible to levy a permit and print the following labels on your mailing envelopes.
The most commonly used permit types are:

- Mediapost with address: For sales campaigns by mail whereby there is an
order slip in the mailing.

provide postage-paid return envelopes.
