For Immediate Release OSC Enforcement Before the Court

TORONTO – The Ontario Securities Commission (OSC) today announced that Sei-Jin Ki of Toronto, Ontario and Carlos DaSilva of no fixed address have been convicted of quasi-criminal charges under the Securities Act (Ontario). Mr. Ki and Mr. DaSilva were convicted on December 13, 2021 by Justice M. McLeod in the Ontario Court of Justice in Toronto. 

Mr. Ki was convicted of the following offences under the Securities Act: one count of fraud contrary to section 126.1(1)(b), one count of trading of securities without registration contrary to section 25(1), and one count of trading in securities without a prospectus contrary to section 53(1) of the Securities Act.

Mr. DaSilva was convicted in absentia of the same charges as Mr. Ki. In addition, Mr. DaSilva was convicted under section 122(1)(c)  of the Securities Act for violating a permanent trading ban order that was issued against him by the OSC in December 2008.

The convictions relate to the sale of more than $130,000 worth of securities in Toronto Scientific Medtech Inc. (“TSM”) to Ontario investors between May 1, 2016 and June 30, 2017. The court found that Mr. Ki and Mr. DaSilva sold fraudulent shares in TSM, made material misrepresentation regarding investments in TSM and that a significant percentage of the money raised was used for the personal benefit of Mr. Ki and Mr. DaSilva. 

Another individual involved in this scheme, Kamal Singh (“Bobby”) Athwal, pled guilty to one count of distributing securities without a prospectus contrary to section 53(1) of the Securities Act on March 24, 2021.
