Blank Canonical URL

[SL_SEM]

So my devs have the canonical URL loaded up on pages automatically, and in most cases this gets done correctly. However we ran across a bug that left some of these blank like so:

Does anyone know what effect that would have?

I am trying to provide a priority for this so I can say "FIX IT NOW" or "Fix it after the other 'FIX IT NOW' type of items".

Let me know if you have any ideas. I just want to be sure I am not telling google that all of these pages are like the home page.

Thanks!
