I'd like to start the answer and then welcome my colleague Mr. Ieraci to add, should he wish.
When federal procurement is undertaken, it's not mandatory that the indigenous business database be used unless it's a mandatory set-aside under the procurement strategy for aboriginal business.
The mandatory set-asides are located in specific areas, for example, comprehensive land claim agreement obligations. Areas where 80% or more of the population are indigenous would be another example. The procurement there would be a mandatory set-aside and therefore the use of the indigenous business database is required. However, in other procurements that are not mandatory set-asides under the procurement strategy for aboriginal business, the database is not mandatory, and therefore vendors would not be precluded from bidding on a contract if they were not on the indigenous business database.
I hope that was clear. I'd be happy to provide more response.
