If you worked full-time (30 or more hours per week), then "total hours" is not relevant. What matters is the number of weeks of employment, and the MINIMUM requirement is 52 weeks of full-time employment. (CIC provides the hourly equivalent so that part-time workers can calculate their eligibility).
You have left out the important details. Was the 3 weeks "paid vacation"? Unpaid leave of absence? Does your Letter of employment include benefits (such as # of weeks of paid vacation?). Did you work a full 52 weeks?
