I live in Toronto where I use my bike for transportation. I have two kids (almost 3 and 6) and been taking them on the bike since the oldest was about 10 months. We have used a bike seat, a trailer and now my oldest is about to go training wheel free. My partner is a bicycle junkie and loves to fiddle with them. I have joined Bike Forum because it looks like a great place to get info.
I lived in Toronto in the 70s, Finch/Islington. I used to enjoy cycling the Humber Valley and Lakeshore. My country rides took me up Weston rd to Holland Marsh, but I expect that is all urban sprawl now. Ocassionaly I would ride in the Don valley.
