The Hegerberg sisters were both on the scoresheet as Norway secured a 2-1 comeback win over Canada in Kobe to be left in the box seat to advance from Group C ahead of the North Americans.
Canada went ahead just prior to the interval through Jenna Richardson, but Norway displayed great tenacity to draw level through firstly Ada Hergerberg just after the break, with elder sister Andrine then claiming a crucial winner 11 minutes from full time.
The architect of both goals was Caroline Hansen, with the Stabaek midfielder a constant menace to the Canada defence throughout the match with her strong running and dribbling.
Norway had the better of a high quality encounter, though Canada had numerous chances to score in the first half, notably through Richardson and Adriana Leon.
After Ada Hegerberg missed a penalty for Norway, Richardson put the Canucks in front by making a perfect run behind the defence to coolly slot home.
After the break Hergerberg the younger made up for her penalty miss by tapping home from close range, after a stunning run into the right side of the penalty area by the impressive Hansen.
The decisive moment of a high octane encounter came from Andrine Hegerberg, who crashed home a perfectly hit left-foot drive from just outside the penalty area, in what was a classy finish to an entertaining contest.
The result leaves Norway equal with Canada on three points, but facing bottom side Argentina in their final outing, while the North Americans must tackle in-form Korea DPR.
“We should have played with more discipline tactically, and try to avoid the mistakes individually, and follow what we had planned,” said Canada coach Andrew Olivieri. “We could have tried to save one point, but I don't think it would have been the right thing to do.”
