The buyer of heated and green canola has laid off the staff at its Foam Lake biodiesel production facility.
Milligan Biofuels website has been taken off-line and those with questions are being asked to contact Hardy & Kelly Inc., a law firm in Calgary.
It is not known how many producers may be left on the hook for unpaid product.
Canadian Grain Commission (CGC) communications manager Remi Gosselin says growers have no protection through the CGC. Milligan Biofuels was no longer licensed by the CGC as of August 6, 2016 because it did not meet conditions of licensing.
"At the time, ads were placed in weekly newspapers across Western Canada to notify grain producers that if they did business with this company that they would not be protected by security held by the Canadian Grain Commission,"Gosselin said.
It's believed about 25 people were employed by Milligan Biofuels prior to entering receivership.
"It would really be a shame to lose Milligan," said Lyle Stewart, Saskatchewan's agriculture minister. "They employ quite a number of people in a smaller town where every job counts. They are a major market for particularly canola that is out-of-condition."
The company was formed in the early 1990's as a way to utilize frozen or unmarketable canola.
