Do cross domain rel canonical and original source tags have to be the same?

[SecuritiesCE]

I have placed content on a partner site using the same content that is on my site. I want the link juice from the site and the canonical tag points back to my site. However, they are also using the original source tag as they publish a lot of news. If they have the original source tag as the page on their site and the canonical as mine, is this killing the link juice from the canonical and putting me in jeopardy of a duplicate content penalty?  Google has already started indexing the page on their site with the same content.
