Sitting on a peninsula jutting into picturesque Lake Muskoka just north of the town of Gravenhurst, the remains of the Muskoka Regional Centre sit, decaying away and being reclaimed by nature. It's a fitting end that the building is consumed by nature, given the original purpose of the facility.

Built to replace the decommissioned R.L. Hearn Thermal Generating Station in the city's Portlands Region, the Portlands Energy Centre is a state-of-the-art, 550MW, natural gas-fired power station that ties into the 115KV transmission system that powers most of downtown Toronto. Rather than sit on the site of the old Hearn plant, the new plant sits on a site adjacent to it.

From anywhere on the lake and islands, the impressive smokestack of Hearn stands tall for all to see. The generating station itself is the largest building in the portlands, easily visible from the Prince Edward Viaduct. The station itself began as a coal-fired plant, but in later years was converted to a gas-fired plant before being mothballed in July of 1983 amid pollution concerns.

Greenwood Shops; the heart of the Toronto Transit Commission's subway repairs program. Here, vehicles that enter are gutted down and see repairs that the other facilities cannot handle, such as the retooling of the trucks (wheels), door pneumatic repairs, or complete rebuilds from the ground up. All in a days work for the employees here.

Envisioned in the 1950's to replace the aging City Hall, New City Hall was to be a modernist masterpiece that would also be a city landmark and public space. And now, almost a full half-century after construction, it still stands out as a striking example of modernist architecture, complete with a central public space in Nathan Phillips Square.

Sitting right between the Queen Elizabeth Way and the Oakville GO Station, and next to a Home Depot store and parking lot is a red brick building with windows covered over by sheets of plywood. The building is fairly easy to miss if you're not looking for it, but once seen, it stands apart from the surroundings. This building is the former Oakville Lifecare Centre, originally built as a hospital for terminally ill patients.

Once the active gateway of the suburbs, the original bus platforms at Eglinton subway station sit unused, sealed off from the rest of the world by walls inside the station, and a fence outside the station.

A single flick of a switch, and 230 kilovolts of power would respond to the call. A flick of a second switch, and an entire neighbourhood would be without power. A third switch, and power would be delivered from a different substation. This all could have been a daily event at the hydro control centre.
