Welcome to NamePros @dg415697 - lots of things to learn and get help with in this amazing online community. @J Sokol has already provided a link with a great place to start. Lots of Canadians (including me) active on NamePros.
Do you plan to concentrate on a specific niche, or not sure yet?
My main advice is start slow, only invest what you can afford to potentially lose, be analytical, focus on names with a significant pool of potential users, and be reasonable in your expectations. Domain investing is not fast, easy or assured.
Believe you find numerous threads and posts on NamePros re the flipping of domain names. This is a large Forum and there are threads and posts on all aspects of domain names - hopefully you will find the threads and posts helpful in your domain name endeavors.
