The Alberta Securities Commission is accusing Platinum Equities Inc. of illegally distributing the securities of a number of real-estate investment partnerships and Platinum’s two principles of failing to properly supervise the company’s activities.

The ASC’s enforcement branch alleges the Platinum group — headed by a brother and sister team — issued misleading, untrue or insufficient documents and promotional materials related to offerings of several business properties and development land, primarily in Calgary.

It says a total of $58.3 million was raised from investors, primarily Alberta residents, for limited partnerships created in 2005, 2006, 2007 and 2008. It says the limited partnerships weren’t registered with the ASC and the money raised was from investors who were unqualified to make unregistered investments.

Shariff Chandran and his sister Chitra Chandran face various allegations as directors, officers and control persons of the limited partnerships and of Platinum.

The Chandrans are accused of failing to properly supervise or train sales consultants, particularly Victor Alejandro Galivan Jaro, also known as Alex Galivan. All three live in Calgary.

The alleged events occurred between August 2005 and July 2010.
