Canadian Natural Resources Ltd. has been given the go-ahead to resume work at part of an oilsands project in eastern Alberta where a bitumen-water mixture was found oozing to the surface last year.

Canadian Natural Resources Ltd. is seeking approval to resume crude extraction from the part of its Alberta oilsands property where a bitumen-water mixture was found oozing to the surface last year.

AER rejected Canadian Natural Resources Limited's request to start steam operations on a site with spills oozing bitumen nonstop since May.
