If the commission is for the production of a work of art, perhaps this is a possibility, found on a Govt. of Canada website:

Ce chiffre, qui ne comprend pas les ventes aux entreprises et aux établissements publics, ni les commandes d’œuvres d’art, ne reflète probablement pas les ventes aux collectionneurs privés.

This figure does not include sales to corporations, nor to public institutions or from commissions of works of art, nor likely does it reflect private collectors.
