GAC-MAC 2021 Hybrid Meeting Postponed to Nov. 1-5, 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) has been monitoring the COVID-19 pandemic from the start and has been constantly adapting and evolving plans. In Fall 2020, COVID-19 numbers were lower and the prospect of a vaccine led the LOC to develop scenarios for a hybrid meeting in May 2021, permitting virtual attendance but also keeping the opportunity for in-person attendance, which was identified in our member survey as one of the highlights of GAC-MAC.

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 1-5, 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.

In the next weeks, we will work with session convenors, and short course and field trip organizers, to confirm new dates and make any necessary changes.

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