The project will use SWT-2.3-101 turbines, featuring a maximum power rating of up to 2.3MW each, and a rotor diameter of 101m at a hub-height of 99.5m.
The contract also includes a three-year service agreement.
Upon completion, the South Kent Wind project will produce enough renewable energy to meet the needs of about 100,000 homes per year, and will allow Ontario to move away from its dependence on coal-fired power plants.
The wind turbines installation is scheduled to commence this year, while operations is expected to start in early 2014.
Siemens will manufacture the blades at its Tillsonburg plant and the towers at CS Wind's factory in Windsor.
Ontario Minister of Energy Bob Chiarelli said the project will provide Ontario with clean, renewable energy and support new jobs in southwestern Ontario.
The project is part of Samsung's $7bn investment in Ontario to build and operate 2,500MW of wind and solar power projects.
Siemens has also opened a Canadian wind turbine service and maintenance distribution centre in Chatham, Ontario, to improve its proximity to its customer base.
Siemens Canada vice president of wind power Jacob Andersen said; "We're encouraged by the overall progress of wind projects in Ontario, are proud to base our Canadian operations in the province and are eager to help to bring renewable energy to Canadians."
