Welcome to the Q&A Forum

My first question back at you is why is your hosting company deciding your canonical structure for you? a hosting company should just host and you should be using canonical tags and .htaccess to sort out your own canonical URLs. So my gut reaction is to change hosting company. After that: Open Site Explorer - put both URLs in and see which ones are being linked to and which has the highest value. If you're not a PRO member then take the 30 day trial and use OSE to sort this issue out. You'll be glad you did. After that... seriously as a web designer & SEO, not having control of my own URLs would annoy the heck out of me, so change hosting provider. That'll be the second biggest favour you could give yourself Slightly opinionated, I know, but at the end of the day it's your website not your host's.
