Travel time matrix and employment statistics for the London Metropolitan Area.

A data frame with origin-destination pairs, travel time by transit, and population and employment by Census Dissemination Area. Census Dissemination Areas (DAs) are the smallest publicly available geography provided by Statistics Canada. Travel times are for a representative day in two different years: 2019 (pre-covid measures) and 2023 (post-covid measures) from the centroid of the origin DA to the centroid of the destination DA. Times are calculated as the median of all times within a 15 minutes window of the departure.
