Last November. I’m walking north along a ravine in the east end. A wide stream, or small river, casually wends its way down to the lake. The river is very shallow, its flow invisible to my eye; the whole thing seems to be buttoning itself up for the incipient winter. After a few twists and turns and over a flood-damaged Toronto parks & rec brand bridge, the trail reveals a glimpse of something shiny in the middle-distance treetops.

A foil-wrapped pipeline is suspended twenty feet over the dirt path, pacing alongside a monument road bridge just to the north. Walking under major streets is a common occurrence in Toronto, shot through with memories of ancient glacial runoff, but I’ve never seen something like this before. Where is it going, and what could it hold? Sewage is most likely, but also the least exciting. Heavy water. Chocolate. Prison escapees. Internet. These are the things I wish I could glimpse rushing along through this inscrutable piece of infrastructure.

Closer examination yields nothing and I leave the pipeline to its business.
