Hi there,
Noticed that you never got a reply on traffic out to Thickson's... I travel west on the 401 every morning between 6am and 7am from Ajax to Mississauga. To be honest, the east-bound traffic from the DVP/404 out to Whitby doesn't look all that bad. I'd try to avoid being at the 401/DVP interchange after 7:30 and before 9:30 if I could avoid it though. Hope that helps, and that you have a birdy visit at Thickson's.
Best,
Pat
