practicality

Oh wise internet - if an employmant ad just says to email my resume, to a given e-mail address, do I attach it, or paste it into the body? It's a .doc file. Also, given my status here, where would be an appropriate place to note that I am legally qualified to work in this country, if I should mention it at all? And yes, work permit arrived today from Alberta, so I am good to go for summer employment.
