Whether you are uncertain about your situation, general legal concepts, or what to bring to your first meeting, our FAQ pages are a one-shop stop for answers.

What information should I submit in the contact form or over the phone?

You should let us know who you are (name, position, name of business), who you are contacting us for (yourself, your business, or on behalf of someone else), why you are contacting us/the nature of your problem. Provide any other details you think are necessary to explain. As executives and managers you should also make sure to tell us: your position title, your current salary, how long you have been employed there, the name of your employer, and whether you were recruited. If you are uncertain, here is a list of things you should include.

 If you are an executive or administrator at a school, please tell us the name of the school before giving us any other information including your name. We represent a number of schools in Montreal, and we do not want you to give us any information if we are already representing your employer. If you are an executive who thinks we might be representing your employer, you should do the same.
