I recently went for a quick trip to the states - left Friday and came back Sunday night - early AM Monday - After I got home, I noticed there was no stamp in my passport to reflect my most recent entry into Canada - not sure why the CBSA officer didn't stamp it - he stamped my customs card I recall. Any insights? is this a mistake and do I need to get this fixed? I have received an ITA and I don't want this to mess up travel/presence in Canada etc.
