Last night'sToronto storm left Union Station looking more like Ripley's Aquarium than the city's central transit hub.

Nearly 70 mm of rain ravaged parts of the city, causing massive floods inside Union Station and the surrounding area.

Inside, one of the newly-constructed moats saw water rolling down the steps like it was trying to catch the last train of the night.

The underground streetcar tunnel that leads to Queens Quay was also flooded, halting streetcars at the platform over the waterlogged tracks.

Meanwhile, the area outside was equally saturated, especially the York Street underpass to the west.

The scene wasn't much better along Lower Simcoe, where many had to wade their way through the fast-moving downpour.

Tonight was borderline chaos at union station terminal. Our major cities are not equipped for storm water management and extreme weather events that will only become more prevalent due to climate change. #onstorm pic.twitter.com/u2IAkH0FBa

As of this morning, Metrolinx spokesperson Anne Marie Aikins reported that the damage had mostly cleared, save for a few leaks here and there.

Despite the flooding, regular service continues in and out of Union, while other parts of the system are still being sorted out.
