Welcome to the Q&A Forum

No, you will not receive any increase in your pagerank as a result. Having said that, if the other website did NOT include the canonical link then there is a chance the link juice for the page would either be split equally between your site and their site or worse case it will all be given to their site (if Google thinks that they are the originator)! So indirectly, ensuring that they add the canonical tag will result in your page having a better ranking. Hope that makes sense! Steve
