My name is J G R G S R. That's how I applied for PR. Somewhere along the process, even though my application was done with my full name, Immigration dropped R G S and I became J G R. I never asked for it. It happened. I never had any concern over it because on any document in Canada, be it my driver's license, bank cards, etc... my name is always shortened. When I filed my citizenship application I asked for my full name to be restored or stated in my certificate. That's all. I never thought it would be an issue. Especially since I wasn't the one who changed my name to begin with.
