Ottawa took it 4-1 in Oshawa, in regulation, with a two-goal first period that set the terms early. The 67's never trailed after that, adding a goal in each of the final two frames.
The opening period went 2-1 to the visitors, and Ottawa led 2-1 heading to the first intermission. A single goal in the second made it 3-1, and one more in the third closed it out at 4-1, with Oshawa held off the scoresheet over the last 40 minutes.
The decisive number is the scoreless back half for the hosts: Oshawa's only goal came in the first period, and Ottawa answered with three straight across periods two and three. Scoring details beyond the period splits were not available.
