Yes, I am a Canadian, and furthermore I am currently doing many projects for a firm in India! My grammar, punctuation, style and sentence structure are flawless because I have a dozen years of experience as a writer/editor. Although the five star review with my profile implies I've only worked for one company through this website, in fact I have worked for him for three months now; he is very pleased with my work!
I do not rely on software programs like "spell check" and "grammar check" because they are tools of a lazy mind. I know English because I speak it, write it, and teach it! Let's work together!
