The Federal Liberals are hinting they may take another look at what they're calling the unintended consequences of their proposed tax changes.

John Barlow the Conservative Ag Critic says Finance Minister Bill Morneau needs to get rid of it altogether.

"The words that he used was 'tweaking,'" Barlow said. "This was not something that needs tweaking - this is something that does not need to happen. The first step is to extend the consultation period into January, 2018."

Barlow says the proposed changes would hit farmers, small businesses and entrepreneurs the hardest.
