Thanks Raman for circling back with this information.
Updated generic form with new child info is Generic Application Form to Canada (IMM 0008) ( Completed and signed by the principal applicant )
Updated family information for me and wife with our child info. is
Additional Family Information (IMM 5406)
Completed, dated and signed by everyone in the following list:
• the principal applicant
• spouse or common-law partner (whether they are accompanying or not)
• each dependent child over the age of 18 years (whether they are accompanying or not)
Right ?
Also looks like we still need to submit Passport copy of non-accompanying child which is contrary to what we discussed here:
