The turbine that collapsed was a GE 1.5MW xle, placed in service in 2011 by US-based Invenergy as part of the 52-turbine (78 MW) Raleigh wind facility in Chatham-Kent in southwest Ontario. The project was sold to Terraform in 2015. No information has been released as to the cause of the failure.

This Vestas V80, 1.8 megawatt wind turbine has been tethered while engineers try to determine why it is leaning to one side.
An 18-inch piece of the serrated edge of a wind turbine blade broke off and was thrown at least 400 feet from the turbine sited in Ontario, Canada. The saw-toothed edges are meant to reduce noise from the turbines and improve the efficiency of the machine. More information can be found here.
