Alias URls

I love your product, but don't understand how to create canonical URLs or structured meta date. I would like to create something like a canonical URL.
Curently my URL looks something like pathologyprevention.com/index.php/en-us/...m-fortifier?Itemid=0

I would like to change it to something like pathologyprevention.com/the-urinary-system-fortifier

Where the-urinary-system-fortifier is a product name in EShop.

Thanks for any direction. I found a couple of plugins that support SEO and Structured metadata, but not Canonical URLs.
