Nah, my father only naturalized within the last five years, so I'm very familiar with the fact that the US certificate has the photo on it (had to get the exact date of naturalization to fill out CIT 0001E for the proof of Canadian citizenship). That made me all the more surprised that the certificate doesn't have the photo on it.
CIC used to issue Citizenship cards with the photos on them along with the certificate but that practice stopped in 2012, now the document that is de facto proof of identity and citizenship is the Canadian passport alone.
Except that a Canadian passport is not considered to be proof of Canadian citizenship. Once when I was in a Service Canada office, I decided to ask a question about my SIN, and the clerk asked if I had proof of Canadian citizenship. I said yes, my passport. She said that's a travel document, not proof of citizenship! Coming from the U.S., where a passport definitely is proof of citizenship, I was incredulous. However, I looked it up, and she was right...Canada does not view a Canadian passport as being proof of Canadian citizenship!
