The Canadian government is to launch an anti-dumping investigation into Chinese modules and laminates.
A short statement published on the website of the Canadian Border Services Agency (CBSA) confirmed the start of the inquiry which will begin with the release of a so-called statement of reasons document that will be made available within the next two weeks.
The investigation is in response to complaints from four Ontario-based firms; Eclipsall Energy Corporation, Heliene, Silfab Ontario and Solgate.
Ontario removed the 60% domestic content requirement from its successful feed-in tariff last year programme after opposition from Japan and the European Union.
The US anti-dumping and anti-subsidy cases will be heard at the International Trade Commission (ITC) in Washington on Monday. If the Department of Commerce decides to impose duties when it gives its final decision next week, it will need the ITC to rule that it has found evidence of injury to the US solar manufacturing sector. The ITC will not give its verdict until mid-January.
