A new report outlining the ten most pressing issues facing the oilsands has been released.

Chris Lee with Deloitte tells 660News the bottom line in their latest study is the need for all stakeholders to co-operate.

Lee says it’s time to stop the “them or us” mentality that exists between oilsands operators and environmentalists.

He says only through co-operation can the oilsands be developed, while at the same time addressing the many environmental issues that are associated with them.
