Toronto - 21, October, 2009 - Thomson Reuters and Alpha today
announced a new suite of initiatives to address market data
fragmentation. Leveraging the two organizations' combined expertise
in the Canadian markets and Alpha's technology facilities, Thomson
Reuters will provide an independent consolidated tape and hosted
direct feeds.

The new suite of services will allow traders to see share prices
offered across the various exchanges and alternative trading
facilities in Canada, including Alpha ATS, Pure, Chi-X and the TMX
Group. The fully integrated and enhanced consolidated data offering
will be derived from order and trade data from the various Canadian
equity marketplaces, and will include access to pre- and post-trade
market data.

Thomson Reuters feed handlers will be placed adjacent to most
information sources including Alpha Trading Systems, providing market
data access at the lowest possible latency. Clients will be able to
access all best bid and offer data from and across all contributing
marketplaces. In addition they will have full order book access
attributed by dealer and marketplace. Furthermore the Thomson Reuters
offering will include time and sales data from the sources.

Jon Robson, President of Enterprise, Thomson Reuters, said: "In
today's evolving market, accessing a complete real-time view of
liquidity is a challenge. This is a significant breakthrough for the
Canadian marketplace, delivering a consolidated view of all liquidity
across multiple venues, enabling each individual trader to operate
with absolute confidence that they are trading at optimum levels for
their clients. Well managed consolidated data is a key means to help
drive efficient trading and market liquidity. We are delighted to be
working with Canadian participants in Alpha to provide this benchmark
standard for the market."

"Access to adequate consolidated market data is an issue of major
concern in the Canadian marketplace. Without it, market participants
cannot discover and exploit the best trading opportunities. Working
in close collaboration with Thomson Reuters will enable us to provide
the Canadian marketplace with a competitive solution that is driven
by the industry and addresses key concerns around cost, reliability,
low-latency and quality" noted Jos Schmitt, CEO of the Alpha Group.
