The solar PV modules will be manufactured by MEMC Singapore in Newmarket, Ontario.
Northland will spend about $600m to develop ground-mounted solar projects in Ontario.
Earlier this year, MEMC started manufacturing solar PV panels in Ontario for SunEdison, its solar energy subsidiary, in order to help the company meet the 60% domestic content requirements of the feed in tariff program.
MEMC is an affiliate of MEMC Electronic Materials, engaged in the design and development of silicon wafer technologies.
