Okay, so here they are. This was the A.V. Roe plant on the day I did a delivery, about a year before they tore it down. I would have liked to take more pix, but there was security and cameras there so I didn't know if they would object. The vid you posted is the inside of the facility, hollowed out. This plant, originally A.V. Roe, then AVRO, then it was bought by McDonnell Douglas, who were bought by General Dynamics and later they sold the building to Magellan Aerospace. There was also an Aircraft hangar and final assembly facility on the corner of Derry and Airport Rd, however this plant is where the finer parts were manufactured. The newer Magellan 'plant' if you can call it that, built next to it is barely a broom closet in comparison, doing minor maintenance and support work for aircraft companies.
When Canada let Avro go, that was it, we were out of the big leagues. Just like after we scrapped our aircraft carriers and our navy became a joke.
Much of the plant was abandoned and unused, even when Magellan occupied it. Note the old 1960s 45' trailer. The name on it was from a company that went bankrupt in the early 1980s after trucking industry deregulation.
Just beyond this pic there was originally an airfield for execs. Long ago removed.
This is the loading bay where once there was airport support vehicles, later converted to load and unload trucks.
I used to get a kick out of the security speaker at the entrance to the plant that the guard talked to me through. It was right out of the 1930s. I had occasion to take more pix just before they started tearing it down, but I didn't like the place. It was insulated with asbestos, which was pretty much the real reason they didn't renovate it. They also tore it down quickly to avoid the fuss of possible heritage people running in there and trying to save it. Anyway, these are the plants last days. Most of the equipment lying around has been abandoned decades ago. Fairly sad, the ghosts of what were and what could have been.
