If you want to add your visitor spouse to your AHCIP, he needs a Visitor Record, not a history report. A VR is issued by CBSA upon entry or by IRCC when applying for extensions.
Note that asking for a VR when entering Canada is a double-edged sword. It shows CBSA more of an intent to live in Canada and therefore increases the risk of being refused entry.
Thanks for the reply! I just checked the form and it's not limited to Visitor Record. Under "other" they have "Legal entitlement to be in Canada - Must be FEDERALLY issued with NAME and BIRTHDATE" and one of the options listed under this category is "Canada entry document". A previous thread I found, the OP had shown her stamped passport to be added to AHCIP. If they're looking for a federal document with name, birthdate, and entry date, then traveler history report could satisfy that, no? I will call tomorrow and check with them. I don't want to ask for a visitor record for the exact reason you stated, that it increases risk of being denied entry.
