The investigation goes back to last December after a business complained of irregular natural gas bills.
Police say they determined that a number of businesses had contracts with Active Energy or Active Renewable Marketing and there were forged signatures from either the owner or employees.
Mounties say they've identified two suspects who were not direct employees of either FortisBC or Active Energy, but were sub-contracted agents working on commission.
After the initial complaint, police sent out 90 other letters to Cranbrook and Kimberley businesses asking them to review their gas bills.
So far, police have confirmed 25 fake contracts and are considering criminal charges of uttering forged documents against the two suspects.
