Can I work in Canada with an old citizenship card?

[Gherna]

I was born to a Canadian immigrant and thus have citizenship. I have a citizenship card but I am a baby in the picture.

I would like to work in Canada but am trying to figure out if I need to get a new citizenship certificate or if I can just got for a passport.

Any help is appreciated!

Get a passport and a SIN.

How, exactly, does a shooting club provide viable information on citizenship and immigration issues? Please explain, rather than looking like a complete idiot.
