My wife and my kid was staying with me since 2014 in Canada and on Feb 2017 she moved to home country along with my kid for delivery . Expecting baby by mid of August. I have applied for PR along with my family and got ITA . My question here is do i need to mention about child delivery in letter of explanation ? . for my case do CIC request for my dependent passport or only my passport during process ? . please let me know how they consider this case ?
