The opening remarks were given by Nicola Jones (President of CSCI/SCRC) and Adam Pietrobon (Past President of CITAC/ACCFC). The keynote speaker was Dr. Timothy Caulfield, who delivered the presentation titled \"Communication in the Era of Misinformation\". Dr. Michael Hill (University of Calgary) received the CSCI Distinguished Scientist Award and Dr. Philippe Campeau (Université de Montréal) received the CSCI Joe Doupe Young Investigator Award. Each of the scientists delivered award winning talks during the symposium titled \"All the King's Horses and All the King's Men\" and \"Understanding Growth Plate Disorders to Better Treat Them\", respectively.
