55th Annual Meeting - Toronto, Ontario, Canada

The 2024 DDA meeting will take place May 12-17 in Toronto, Ontario, Canada, on the campus of the University of Toronto

As we did last year, we will have a five-day format that incorporates a hybrid approach with a robust attendance experience for both in-person and remote attendees.  Furthermore, it is a priority for us to continue improving the experience for poster presenters, both in-person and remote.

Visa Advisory:  If you reside outside Canada AND if you are a citizen of a country designated by Canada as visa-required, then we recommend starting IMMEDIATELY on the process of obtaining a visa if you intend to enter Canada and attend the meeting in person.  Visa-processing times in Canada have been reported to vary widely from a few weeks to many months.  If you wait until the SOC announces the scientific program, then it is very possible that your visa will not arrive in time.  If you have questions about this process, please email the Local Organizing Committee Chair, Sam Hadden (sam.hadden<at>

  • Getting to Campus:

    Toronto has two airports, Peasron International Airport and Billy Bishop Toronto City Airport. Note that Billy Bishop is particularly convenient (nearly walking distance from campus) if you happen to be coming from a location that has connecting flights. Also note that if you are flying out of Pearson back to the US, you will go through US Customs at Pearson, so you may want to budget some extra time when getting to the airport for your return flight. 

    Additional travel information can be found here.

  • Accommodations:

    A block of rooms at the New College on U of T’s campus has been reserved for DDA attendees. Room rates are $60 CAD / night for singles and $85 CAD / night for doubles plus tax (13%). To reserve a room fill out the PDF form. A one-night nonrefundable deposit is required to book.  We recommend booking early, as reservations are filling up fast. 

    There are many hotels and lodging options near campus, and elsewhere in Toronto, though they can get expensive.

Mentoring from the DEI Lens

Features: Dr. Sherard Robbins (Visceral Change)

The Missing Link: Mentorship as The Key to Success

The talk will focus on the importance of mentorship for students, postdocs, and faculty. Using a multicultural lens, this session will explore the ways in which cultural and social identities impact how people connect with one another while providing helpful tips to create space to celebrate our diversity; when done correctly, this will lead to a collectivist approach to growth and development.

Dr. Sherard Robbins serves as the Founder, Owner, and Principal Trainer of Visceral Change. For close to a decade, Dr. Robbins has operated as a multicultural organizational development consultant, helping organizations and institutions across the country and abroad find new and creative ways to center their professional framework around diversity and inclusion. He has championed efforts to address and exact social change both nationally and internationally and has been highly revered by corporations, councils, and institutions across the globe.

Public Talk

Tuesday, May 14, 7 pm. 

Dr. Samantha Lawler "Internet for all? The painfully high costs of megaconstellations for astronomy, the atmosphere, and the future of LEO"

Dr. Samantha Lawler is an associate professor of astronomy at Campion College and the Department of Physics at the University of Regina in Saskatchewan. Her research work on Kuiper Belt orbits and predictions for satellite pollution has been featured by CBC, CNN, NPR, Scientific American, The New York Times, The Los Angeles Times, Wired Magazine, Nature, and many other international news outlets.  She lives on a farm outside Regina and deeply appreciates the beautiful prairie skies.
