This is the route we take nearly every every (though there are about a thousand variations possible). There's only one road to cross, and a short trip down a quiet dead-end street. From there it's all multi-use pathway -- a nice feature of south Ajax is that there are a lot of these pathways between houses and neighborhoods. The school bike racks & kindergarten doors are just across the grass to the left of where the video ends -- where you could momentarily see a lot of people milling around waiting to pick up kids.
(The weird "underwater" warble you may notice in the video was added by youtube's attempt to "smooth" the camera vibrations... I don't think I'll be trying that again.)
