Item 1.01.             Conflict Minerals Disclosure and Report

Conflict Minerals Disclosure

Canadian Solar Inc. (“CSI”) is a leading vertically integrated provider of solar power products, services and system solutions with operations in North America, South America, Europe, Africa, the Middle East, Australia and Asia. CSI designs, develops, and manufactures solar wafers, solar cells and solar power products. CSI’s solar power products include standard solar modules and specialty solar products. CSI is incorporated in Canada and conducts most of its manufacturing operations in China. CSI’s products include a range of solar modules built to general specifications for use in a wide range of residential, commercial and industrial solar power generation systems. Specialty solar products consist of customized solar modules that CSI’s customers incorporate into their own products and complete specialty products, such as portable solar home systems.

The disclosures herein for the reporting period from January 1, 2015 to December 31, 2015 are presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934, as amended. According to section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the definition in the Form SD and for the purposes of this assessment, conflict minerals are defined as columbite-tantalite (coltan), cassiterite, gold, wolframite, and their derivatives, which are limited to tantalum, tin and tungsten.

Description of Reasonable Country of Origin Inquiry

CSI has taken the following steps as part of its reasonable country of origin inquiry to determine whether the conflict minerals may have originated in the Democratic Republic of the Congo or an adjoining country:

·                  listed out the materials and equipment used during the production of its products;

·                  determined which conflict minerals were necessary to the functionality or production of products manufactured or contracted to be manufactured by CSI (“necessary conflict minerals”);

·                  identified the suppliers whose products contained necessary conflict minerals (“Suppliers in Concern”);

·                  requested that Suppliers in Concern provide a statement on where they obtained their products and materials that contained conflict minerals and requested that they provide certificates of origin for these products and materials; and

·                  analyzed whether the necessary conflict minerals used by CSI during the reporting period may have originated from the Democratic Republic of the Congo or an adjoining country or whether they were from scrap or recycled sources.

CSI determined that during the reporting period, the only conflict mineral necessary to the functionality or production of products that it manufactures or contracts to be manufactured was tin. In the processing of solar modules, the company uses copper strip which is coated by tin. In addition, solder used in junction boxes and for other purposes contains tin. CSI has made inquiries with all its suppliers of tin-containing products about the source of the tin used in their products and further requested that these suppliers provide confirmation and supporting documentation of origin for the tin contained in their products. CSI does not make purchases of raw ore or unrefined conflict minerals and makes no purchases in the Democratic Republic of the Congo or adjoining countries.

Determination

Based on CSI’s reasonable country of origin inquiry, CSI has no reason to believe that its necessary conflict minerals may have originated in the Democratic Republic of the Congo or an adjoining country.
