US Military Upgrade to TS SCI -Some Family in Canada

Hello all, I am Active Duty military. I am upgrading from Secret to TS SCI for embassy work. I have a foster brother and sister living in Canada as US citizens with permanent residency. They may be considered immediate family members by some definition but I dont consider them immediate family.
I heard that Canada has a bit a “relaxed” status when it comes to these kind of issues on the eQIP.

Please advise. Thank you!

Just put everything down in your eQIP in additional notes. The investigator may care but the Adjudicator is the one that will make the final ruling. I would maybe put this in the foreign relations section.
