Who can I list as a dependent?

Coverage is only applicable to your spouse (common-law included) and children (step, legally adopted + incapacitated over the age of 25 years included). Children are covered without exception up to age 19. Between the ages of 19 and 25 children can continue coverage; however, they must be in school full-time as evidenced by a letter from the respective institution at the start of each academic year.
