The pair were scheduled to meet Tuesday but heavy rain on the previous day forced a backlog of matches in the bottom half of the women's draw.
World number four Wozniacki, last year's U.S. Open finalist, wasted little time in dispatching her error-prone Canadian opponent for the sixth time in seven encounters.
Wozniak's only victory was when Dane Wozniacki retired injured from their match in Tokyo last year. Wozniacki will meet Germany's Julia Goerges in the second round.
