Claims for reimbursement for any expenses from any of the benefit plans must be submitted to Sun Life within 90 days of the end of the calendar year in which the expense is incurred. This means that the deadline for submitting claims incurred between January 1 and December 31, 2018 is March 31, 2019. Claims must be received by Sun Life by this date. If submitting claims by mail, please allow a minimum of 5-7 business days. If you miss the deadline you will not be reimbursed for your claims incurred. This deadline applies to 2018 claims made under the Dental Plan, Health Plan or Flexible Spending Program (Health Spending Account or Personal Spending Account).
