Does your fax is a direct line? If so all you have to dial is 001+ten digit phone number.

If you are dialing from a company you may have to dial a code or number to get an external line connection. Once that is done you still dial 001+10 digit number and that should do it.

Nevertheless please check the following link to have the right "area code" in Canada.
