That instruction is for IMM0008 not IMM 5406. If you did that for IMM 5406, then you have missed information of adult children (including yourself)I notice a lot of IMM 5406 request here, we were ask for this as well and its weird cause I remember filling up the webform at the beginning and they specifically said that put only the children that are eligible to accompany and not the ones that are not and the children that are already in Canada PR/Citizen. And now they're asking again to send the forms cause we "send an incomplete file".
