For the time being, please pick up a hard copy of the Forseen Absence and Vacation Form

how to report: use the tdsb schoolmessenger app or call the automated safe arrival line at 1-833-250-2290 .
when to report: report the vacation as a "future date" absence as early as possible before the trip to stop automated calls. [1, 2]

extended absence form: you must request, fill out, and submit an extended absence form from your school’s main office. “a planned absence of more than 4 days requires the completion and submission of an extended absence form from the main office requiring the signature of all your teachers and your vice principal at least 10 days prior to the absence.” -- [attendance - toronto district school board ]. [1, 2]
coursework: students are fully accountable for catching up on missed material. teachers are not obligated to prepare advanced homework packs. [1, 2]

the "demit" rule: if a student is absent for more than 15 consecutive school days for a vacation, the tdsb is legally required to demit (remove) the student from the school register . [1, 2]
re-registration: upon your return, “you may need to register your child again when you return provided you still reside at an address within the established boundaries of the school.” -- [highfield junior school - toronto district school board ]. your child's exact spot or specific classroom cannot be guaranteed. [1]
program of study exception: in some instances, parents can speak with the principal in advance to request a formal program of study . if approved, the student may access online ministry of education resources, which may prevent them from being demitted. [program of study-tdsb]
