Nicely done there, however, I have to agree, using canvas for a website is a no-no, take this advice from someone who's been doing web design and development for 5+ years ;)
However, like someone said on this thread, don't rule out the possibility to use canvas where it can be most powerful, someone suggested a gallery, you can build one of them pretty easily using canvas, or using C2.
What someone looks for on a webpage is how fluid the website is, all websites have to look professional, and whilst yours does, it still lacks basic input, like Tom said before, 'Copy & Paste' is a big factor, and also right click, not many people would right click on a website, unless they were to save an image or something else, but you can take this feature out with standard javascript anyway.
Anyhow, with that said, nice job on the website, and I spotted a little error for you ;) - When you cycle through the pages and go back to services, your text needs a little indentation from the left of the screen, here's a screenshot just to show you.

Have fun!
