The blame for the sad affair that kept Torontian, Suaad Haji Mohamud, a Canadian citizen from returning from Kenya because both Kenyan and Canadian consular personnel didn't believe that she was the person portrayed in the photo can probably be blamed on her Canadian passport picture:
In all honesty, would you let her through if it was your decision at the border?
Here is some of her other ID.
Both her OHIP card and her driving license, where she is wearing a hijab are impossible to match to the picture on the left.
However in the ID photo where she isn't wearing the hijab, even though her hair style is different, clearly resembles the picture on the left.
Instead of banning smiles from passport pictures, officials might want to consider banning hijabs instead.
But this being Canada........
