The government’s policy as established by Treasury Board is to pay within 30 days, from the time "
an invoice is received or the goods or services are accepted, whichever is later". A department is also required to pay interest on any amount that is paid late unless they notify you within 15 days of a problem with the invoice, the goods or services.
If you do not receive the money owed after 30 days, whether it is the invoiced amount or the interest, it may be helpful to contact the client. If you have no success, it may also be helpful to contact the contracting officer.
Request payment by direct deposit
The Government of Canada is committed to reducing the number of cheques issued and is promoting direct deposit as the fastest and most effective method of receiving payments. Businesses that supply goods and services to the Government of Canada should enrol in direct deposit for accounts payable, as well as for grants and contributions.
