Dealer’s Certificate:

At each place where the dealer is authorized to trade, the dealer must post the certificate of dealer registration so the public is likely to see it (this does not apply to an "Outside Ontario Dealer," a "Lease Finance Dealer" and a "Fleet Lessor," who must keep the dealer’s certificate at the place of business and produce the certificate for inspection upon request by any person).
While engaged in dealer activities, an individual dealer must carry his or her certificate and produce it for inspection at the request of any person.

Salesperson’s Certificate:

At each place where the dealer is authorized to trade, the dealer must keep a copy of the certificate of each registered salesperson who trades from that place and produce that copy for inspection upon request by any person.
While engaged in dealer duties, the salesperson must carry his or her certificate and produce it for inspection at the request of any person.
