OINP Name issue

[xendron]

I received an ITA for a non-EE stream of OINP. My name in OINP profile is:
First name: X Y
Middle name: (blank)
Last name: Z

The name on my passport is:
Given name: X Y
Last name: Z

But my name in reality is as follows:
First name: X
Middle name: Y
Last name: Z

In some documents my name is X Z and in some it is X Y Z. Can this cause any issues?
