The cabin was empty and nobody was injured in the incident. The company says the cabin fell during routine testing of the new gondola.
The company issued a brief statement saying, "Doppelmayr, manufacturers of the lift, and the British Columbia Safety Authority are working with Sea to Sky Gondola staff to determine the exact nature and cause of this incident."
The Sea to Sky Gondola is being built as a new tourist attraction north of Vancouver, which is expected to open in May. It is not connected with any ski resort.
