Hey guys, hopefully this isn't too far out of the city to offer suggestions, but here's my problem:

I'm planning a ride from East Oshawa to central Vaughan.

I'd like to keep the route safe, but don't want to detour so far out-of-the-way, so a 4h one-way trip becomes a 7-hour one, since I'll still need to come back on the same day.

I'll obviously need to avoid the waterfront trail, as it's quite out of my way. So, my options are either taking HWY 7 or Taunton/Steeles.

Google street view shows me some pros and cons to both, but they also lead to totally different parts of Markham, and some cycling infrastructure there seems either disconnected or forces me to take some rather busy roads.

Has anyone taken HWY 7 or Taunton/Steeles between Pickering and Markham by bike? Any thoughts would be much appreciated.

EDIT: Finch Ave. looks to be another option.
