The briefing will be provided by Greater Toronto Airports Authority (GTAA) President and CEO Deborah Flint at 10 a.m. Almost a month ago, the GTAA said the chronic delays that plagued the airport this summer had “improved”. But just a week later, the airport was ranked the worst in the world for flight delays. Since then, Pearson has introduced a new feature to save time while traveling. The ArriveCAN app now has an advance declaration option that allows users to submit customs and immigration forms up to 72 hours before they arrive. The Pearson press conference will be broadcast live on CTV News Toronto.ca.
