I have canvas bags from 2009/2010 and they don't wear down like that. Those areas look like cuts to the fabric (with fraying along the cut marks) rather than the material naturally wearing down. Did you purchase this bag at the boutique or online such as ebay (and had it authenticated)?
You can bring it in to the boutique and the SA will send it out for repairs but you will have to pay for the repairs. There is also a $20 assessment fee which if you decide to go with the repairs, it will be included in.
