The opposition to the federal government's proposed tax reforms is based on misleading information. That is the view of Dennis Howlett, executive director of the lobby group Canadians for Tax Fairness .

Small business owners, including farmers and doctors, have been arguing that if these changes are implemented, they will constitute an attack on the middle class.

Finance Minister Bill Morneau says the proposed changes to the way small businesses are taxed, are based on fairness. (Sean Kilpatrick/THE CANADIAN PRESS) Howlett says that is not true. More than 90 per cent of those who would be affected earn $150,000 a year or more.

"You can't say, in any way, it's going to affect the middle class, and to suggest so is completely misleading. I fear we've got the importation of the American-style politics of lying coming to Canada, and I'm really alarmed by that," says Howlett.

"Some Canadian politicians think this is a good idea: let's just mislead people, who cares if there's any data to back up the claims."

Dennis Howlett of Canadians for Tax Fairness says the proposed reforms will affect the super-rich, not the middle class. (CBC) He disputes many of the arguments that have been put forward in opposition to the government's tax proposals.

"Rich doctors and the small business lobby groups have managed to convince many of the small business people who are not in fact affected at all, to jump on this bandwagon, by exaggerating the fears," Mr. Howlett says.

"Really, unless you're earning $150,000 or more, you're not going to be affected much at all."
