I'm pleasantly surprised that commute times seem to fall within the 15-45 minute mark. By assuming the median is 30 minutes, it suggests that our commute times are closer to 60 minutes per day rather than 80 as some studies suggest.
This may also be in part due to the urbanized nature of posters on these boards. In the house I grew up in, besides work which was about a 20 minute walk away my commutes to college/university and into the city were always in the 90 minute range. Before Viva, 120 minutes each way was not uncommon!
Even where I am now, a 10 minute walk of the Richmond Hill GO station, I had a work placement at CUTA last year, which is located one block north of Union Station. My door to door trip usually came to 70 minutes.
