The electronic slips for anyone who opted in to receive the electronic format before February 17th should have their slips available by February 19th. The printed slips, for those who have not opted in, will be mailed out by the last day of the month. Employees who are no longer active will receive their T4s in the same delivery method mentioned above. Employees still have the ability to opt in on the Mosaic portal to receive their T4s electronically.
