Concerned Canadians can comment on the proposals at, but they have only until October 2.

“In 10 years at the Canadian Chamber, I’ve never seen an issue that has generated greater concern among our members,” says coalition member Perrin Beatty, president and CEO of the Canadian Chamber of Commerce, in a release. “To make matters worse, allotting only 75 days for comment in the midst of the summer holidays is not a consultation. It’s a stealth attack on farmers and family businesses.”

He says most of the chamber’s 200,000 members are small and medium-sized entreprises, and they’ll be contacting their MPs to say the proposals must be scrapped.

The coalition has presented a letter to Finance Minister Bill Morneau asking the government to take the proposals off the table and instead meet with the business community to address any shortcomings in tax policy affecting private corporations.
