A well-known evangelical crusader is claiming credit for the federal government's move to deny tax credits to TV and film productions that contain graphic sex and violence or other offensive content.

Charles McVety, president of the Canada Family Action Coalition, said his lobbying efforts included discussions with Public Safety Minister Stockwell Day and Justice Minister Rob Nicholson, and "numerous" meetings with officials in the Prime Minister's Office.

"We're thankful that someone's finally listening," he said yesterday. "It's fitting with conservative values, and I think that's why Canadians voted for a Conservative government."

Mr. McVety said films promoting homosexuality, graphic sex or violence should not receive tax dollars, and backbench Conservative MPs and cabinet ministers support his campaign.

"There are a number of Conservative backbench members that do a lot of this work behind the scenes," he said.

Mr. Day and Mr. Nicholson said through officials yesterday they did not recall discussing the issue with Mr. McVety.

Canadian Heritage officials confirmed yesterday they will be "expanding slightly" the criteria used for denying tax credits to include grounds such as gratuitous violence, significant sexual content that lacks an educational purpose, or denigration of an identifiable group. More details are promised next week.

Arts groups say they will fight the change. Director David Cronenberg and other big industry names warned that the edgy, low-budget films that have garnered Canadians international acclaim will be at risk.

Conservatives deny that the changes are driven by politics or Mr. McVety, noting the previous Liberal government pledged to review the guidelines as far back as 2003.
