Thanks Treker,
I did see this site previously and unfortunately my suspicions have been verified. Markham just does not have a family friendly way of biking right now. I am referring to pulling a kid cart behind my bike with the little dude it it enjoying a leasurely ride. The closest that we have gotten so far is driving on side streets, some of which are marked with a "bike route" sign between point A and B however until my little guy gets big enough to ride his own bike, the trails are really off limit except for hiking for us.
Thanks again for your reply.
