They've been pressing the Liberals about keeping up their end of a deal that had the NDP support last spring's budget - a 15 per cent car insurance rate reduction.
Now, Newstalk 1010 has learned a report set to be released in the morning will reveal over the past six months, auto insurance rates have gone down by just over four per cent.
The Financial Services Commission of Ontario is behind the numbers.
This is on track with the liberal governments promise to reduce rates by 8 per cent over a year and 15 per cent in two years.
Earlier the NDP had complained about the slow progress of this promise, which was an NDP budget demand last spring.
