REL canonicals not fixing duplicate issue

[Ocularis]

I have a ton of querystrings in one of the apps on my site as well as pagination - both of which caused a lot of Duplicate errors on my site. I added rel canonicals as a php condition so every time a specific string (which only exists in these pages) occurs. The rel canonical notification shows up in my campaign now, but all of the duplicate errors are still there. Did I do it right and just need to ignore the duplicate errors? Is there further action to be taken? Thanks!

You should only worry if GWT reports them as duplicates. I believe SEOMoz tool does not take canonical into consideration when they report duplicate pages.
