Genuine Mackenzie Valley Fur Program

Guaranteed Advance (GMVF)

What is the program?

The Genuine Mackenzie Valley Fur Program (GMVF) (GMVF) provides Guaranteed Advances to trappers in the Northwest Territories (NWT) delivering prime fur and beaver castors for sale. The amount is influenced by the anticipated market performance. Pelts and castors need to be in good condition in order to be eligible for consideration. Advances are reconciled when the item is sold and if items sell for less than the advance in auction, the GMVF program absorbs the cost.

If you are interested in participating in the GMVF program or would like to learn more about the industry, contact your local or regional Environment and Natural Resources office.

Who is eligible?

How much is the advance?

  • The prices are influenced by the anticipated market price and determined by the Traditional Economy Advisory Committee. The value is pre-determined for each species. If the fur or castor sells for more than the Guaranteed Advance price, the trapper receives the additional proceeds and may be eligible for a Prime Fur Bonus too.  

How do I get the Guaranteed Advance?

  • Bring your furs or castors to your local Environmental and Natural Resources (ENR) office.
  • Register in the ENR database.
  • If the fur or castor is eligible for a guaranteed advance, you will receive cash from the officer.
