Hi Shaz,
You may want to ask this question in the 'Visitor' forum of the website. I think they may be able to help you better.
Good luck to you and your boyfriend obtaining a visitor visa. As most people in this forum have experienced, it is not that simple to obtain one. The biggest thing is to convince the immigration officer (IO) that your boyfriend will return back to Lebanon, not to mention, he will have to have a stellar resume for the IO to even consider accepting his application.
Sorry to be blunt but make sure you read/research plenty before your boyfriend plans to submit an application for a Canadian TRV. Check out the site (
www.cic.gc.ca) and this forum and others like this for questions/advice.
