I submited this website in June. This week I e-mailed the editor and she told me that the site is listed in
Shopping: Visual Arts: Posters and Prints: On Canvas
But I can't find it there. Please advice. Thanks for your time.

It's there. Colours Art Publishers <img src="/images/icons/smirk.gif" alt="" />

It's there in http://dmoz.org/Shopping/Visual_Arts/Posters_and_Prints/On_Canvas/ but if you are looking at a downstream data user copy (such as Google) it may take a while. They update to their own schedule. Google used to be around 4 weekly, some sites copies are several years old.

You are right, it is there. I apologize for my ignorance.
Thank you for your time.
Kind regrads.
