Networking sessions for the Monday lunch hour: 12:05 – 12:55

The idea of the networking sessions is to give students and young professionals the opportunity to meet some of the other attendees, which may not be as easy in this year’s virtual format as it used to be during in-person meetings. The hope is that folks show up in the sessions they are interested in, ask questions, and then move to other breakout rooms for small group or one-on-one discussions.

There are 5 networking sessions set up in the following breakout rooms (see more details on each session below):

  • Provincial Government Session
  • Natural Resources Canada Session
  • United States Agency Session
  • Industry & Consultants Session
  • University Session

While we organized for some folks to specifically attend these sessions to be available for students and young professionals for discussions, please join the session that you fit in and participate. Once folks introduced themselves small groups can move into other breakout rooms as needed.

Provincial Government Session:

In this session, several employees from the British Columbia and Alberta provincial government introduce their groups within the government, talk about their job responsibilities, and discuss what skill sets they are looking for in new hires.
