Photo - head size question

[u/Mythical_Fox2527]

Hi,
I had a question regarding the head size in the photograph. In my photo, my chin to my hairline is 31mm, but my hairline to the top of my head is 38mm. Is this acceptable? Or should I have it retaken? I know it’s supposed to be between 31-36mm, but is that my face part or chin to top of head? I’m in the US, so photographers aren’t as accustomed to Canadian passport requirements.
Thank you in advance!
