Can't find the actual article, but what was recommended did indeed happen. Adding the tax-free allowances to salary, plus factor in the increase to personal income tax and voilà a great increase in pensionable earnings.

PM in line for 42% raise -MAY 30, 2001
The three-member commission, headed by Ed Lumley -- who was a minister in the last Trudeau cabinet -- recommended substantial increases to "attract, motivate and retain" quality people in politics. MPs currently earn $69,100, plus a tax-free allowance of $22,800. That equates to a pretax income of $109,500. Mr. Lumley urged the government to abolish the tax-free allowance and increase the salary to $131,400, an effective increase of 20 per cent. Senators would see their salaries rise to $105,840 from $88,200
