Too much rel="canonical" has negative seo impact?

I have a website using gtranslate. But recently, I excluded several contents to be translated. Now, they are using rel="canonical" tag pointing to the main article. However, these untranslated contents are also being indexed to google. Since this is duplicate content but it is using the rel="canonical", will it hurt my overall SEO?

Bump. Need some opinion or feedback on this matter.

Scenario 1: Every page must have a single self referencing canonical. If you want to have a translated version of a page, use hrefLang tag and a rel canonical.

Scenario 2: If you meant multiple canonicals on a page, I haven't tested that, but I just added it to my list. However, I tested having multiple DNS prefetch and preload attributes, it resulted in a ranking loss for the tested page.

Feel free to DM with specifics.
