Articling is the Canadian equivalent of a UK Training Contract or Pupilage. It is generally 10 months in length (depending on province) and cannot be completed until after an International lawyer has received his or her NCA Certificate. Landing one of these is a requirement to becoming a fully qualified lawyer in Canada. While you can do your Articling either before or after you write the provincial Bar exam, you will not be officially "called to the bar" until you complete the full work term required.
