April 29 (Reuters) - Canada's biggest restaurant chain Tim Hortons Inc THI.TO said it will build a C$30 million coffee bean production and roasting facility in Hamilton, Ontario to improve efficiencies and quality control, and will create 50 jobs when it is operational.

The 74,000 square-foot plant is expected to be operational by the fourth quarter. It will generate about 80 construction jobs and when fully operational, the plant will create 50 permanent positions, the company said in a statement.

Tim Hortons operates a second coffee plant in Rochester, New York. When fully operational, the two plants will produce about 75 per cent of the company’s coffee requirements, it said.

The facility will also house a research and development center.

Shares of the quick service restaurant closed at C$29.35 Tuesday on the Toronto Stock Exchange. (Reporting by Isheeta Sanghi in Bangalore; Editing by Gopakumar Warrier)
