GAC-MAC 2021 hybrid meeting postponed to Nov 3-5, 2021 

Dear GAC-MAC community,

As you are aware, the 2021 annual GAC-MAC meeting is being hosted by the Department of Earth Sciences at Western University, London, Ontario. The Local Organizing Committee (LOC) continues to monitor the COVID-19 pandemic and has been constantly adapting and evolving plans.

Ontario has recently moved into a State of Emergency and the number of COVID-19 cases are rapidly rising across the country, and internationally. Given this situation, the GAC-MAC 2021 LOC has made the difficult decision to postpone the meeting to November 3-5, 2021. With the goal of the government to have all Canadians vaccinated by September, the goal of the LOC is to offer a GAC-MAC meeting with the traditional in-person focus – providing opportunities for networking, informal discussion and feedback, and social events – but still with the option for virtual presentations and participation.

Please check the GAC-MAC 2021 website ( for new abstract submission and registration dates, and other information pertaining to the rescheduled annual meeting.
