The ministry operates on a monthly processing cycle.
Submissions received by the 18th of the month will typically be processed for approval the following month. When the 18th falls on a weekend or holiday, the deadline will be extended to the next business day. MCEDT submissions received after the 18th may not be approved until the next monthly processing cycle (i.e. submissions received on Nov 18th will appear on the December RA, submissions received after November 18th may not appear until the January RA).
The ministry recommends that claim files be submitted weekly.
Its a good idea to combine weekly submissions with an extra submission early on the day of the dead line.
