I live NE of Toronto and have occasion to go SW...say to Hamilton or Niagara Falls. There is no doubt that the optimal way (of course allowing for tolls) is to travel west along Hwy 407 to its very west end where it meets up with the 403 or QEW. This would be especially true if one had an IQ model as I do with a GO730. But I am unable to have it take such a route. Instead it will have me take the 407 only until Hwy 400 and then down to the yucky 401 and across. Just wondering what is your experience?
