The federal conservative's associate agriculture critic says the Liberals proposed tax changes are just the latest in a long list of moves that have hurt Canadian farmers.

Alberta MP John Barlow notes the proposed changes would be devasting to farmers, as it would become more difficult for family farms to pass on to the next generation.

He adds the changes would also make it more difficult to plan ahead.

"They plan years in advance," Barlow said. "Whether it's putting money aside for new equipment, new machinery, investing in trying to purchase land and expand other operations. So when you take some of those tools away it makes it extremely difficult for them to plan."

Barlow said it also didn't make much sense to have the consultation period right in the middle of harvest.

"Farmers don't have time to be putting pen to paper, to be reading the potential impacts, to be talking to their accountants, and these things are so complicated, so convoluted, that many accountants can't possibly predict all the possible scenarios on how this is going to impact them," Barlow said. "We are going to be asking the Liberal government to extend the consultation period because you can't make a decision like this on 70 days notice, this is something that is going to take a lot of time."
