Thinkorswim, a Chicago-based online brokerage firm, today announced its expansion into Canada. Canadian traders and investors will be able to open thinkorswim accounts and trade using thinkorswim’s trading technology and participate in its educational programs.

Thinkorswim is now available to residents of Ontario and the company is working toward obtaining regulatory approval in Canada’s other provinces.

The online brokerage offers customers a broad range of products including equity securities, fixed income, index products, options, futures, other derivatives and foreign exchange.

“The growing sophistication of self-directed traders in Canada has matched that of traders in the U.S.,” says Tom Sosnoff, president of thinkorswim. “We are very excited to be able to offer our top-ranked trading platform, research and option training to the Canadian market. The technology that thinkorswim has developed appeals to all active traders.”

Thinkorswim, a unit of Investools Inc., is renowned for pioneering several industry firsts, such as streaming audio and video, professional analytical tools for the retail trader, and trading classes taught by veteran market makers. In September 2007, thinkorswim became the first retail brokerage licensee of CNBC Plus, integrating CNBC’s streaming video content into the thinkorswim trading and research platform.

“Thinkorswim is widely recognized for delivering innovative trading products using the latest and most efficient technology,” says Sosnoff. “We are now bringing this leading edge platform, which has made us Barron’s top-rated software-based online brokerage, to serve the needs of active investors in the rapidly expanding Canadian market.”

thinkorswim provides unique front end trading platforms that allow its customers to trade electronically and provides sophisticated trading tools and analytics, including tools for implementing complex, multi-leg options strategies. The products and services offered by Investools Inc. have received numerous accolades from third parties including thinkorswim’s ranking by Barron’s as its top rated software-based online broker and best for options traders (2006 & 2007), and Prophet’s top Barron’s ranking for best technical analysis tools (2006).
