One shift worker complained about the focus on Monday-Friday. As Environment Week is in fact a 7 day event, the event should expand to be 7 days. (See PR#429105).
It will be necessary to change the way that comparisons between cities are done. Waterloo Region suggested that rather than use Wednesday to compare between cities that do the entire week and those that just do Clear Air Day, that an average participation should be calculated. This would also be more fair between cities were there are more vs less shift work.
This may also interact well with the desire to expand the event beyond work trips.
