TORONTO - Opposition Leader Tom Mulcair is vowing to fight for transparency.

This, in the face of the shroud of secrecy he believes has spread over Parliament Hill under the Harper government.

The NDP leader says when it comes to keeping public information under wraps, the Harper government is unlike any ever seen in Canada.

Mulcair says by axing statistics-producing agencies such as the National Roundtable on the Environment and the Economy, the government is going beyond simply restricting access to information.

He says the government wants to prevent inconvenient data from being generated in the first place.

In a speech to the Canadian Association of Journalists yesterday, Mulcair said his party will keep fighting for transparency.

Mulcair made the comments a day after the CAJ granted Stephen Harper's Conservative government this year's Code of Silence Award.

The award recognizes Canada's most secretive government or publicly funded agency.
