Have you heard of Deviantart? It's an online community of artists. You can submit your art to be viewed by others. You can also sell your art on different items there.
No i haven't heard of them but i will look into that, seems like something that would help me
That's a great community of artists. There's also a website called Redbubble which is more geared towards putting your art on more products which you can then sell. 
Oh that would be great to have some of my artwork on mug, bag and thing like that. 
Redbubble has over 700,000 independent artists. You can put your art on anything from pillows to shower curtains to backpacks and so much stuff, even clothing. It's very easy to use.
I will check them out, i usually paint realism paintings so that would be nice to see on things
It's so worth it! It only takes a little bit of your time to put your work onto the internet. After that, people can buy stuff if they want it. You'll feel great when they do! It'll be further motivation.
I want to start selling canvas  paintings of people and animals 
Well, in addition to those two sites, I recommend you use Wix.com to create yourself a free website as a starting point, where you can sell your original canvas paintings. You can create your website for free there.
I already have a website i just need to update it and add more things
That is great! You are on the path of turning a hobby into a career! Good luck!
