Name issue

[xendron]

I had mentioned in my OINP application that I have been known as "X Z" as well as "X Y Z". "Y" is my middle name and I had mentioned it as part of my first name and mentioned it as my alias in OINP application. Should I mention this as an alias name with IRCC? During my other TR applications like WP and SP I had mentioned that I have not been known by any other names and my Given name is "X Y", and last name as "Z"
