It's obviously difficult without knowing the website but I would say off the top of my head it could be a lack of links to your site to make it an authority, try asking the sites talking about your site to link back to your pages and I am sure that will solve the problem. Canonicalisation doesn't sound like the issue. Just some link juice needed in my opinion.
