Retire Your Ride, a government initiative to get cars more than 15 years old off the road, will come to an end on March 31.

The $92-million program was launched two years ago to recycle old clunkers. Credited recyclers would remove the fuel, oils, coolants and mercury switches present in older cars.

About 600,000 cars were retired in Ontario last year, with about 25,000 of them going through the program.

Retire Your Ride Manager Rebecca Spring says owners would get $300 for their vehicles, in addition to other incentives.

"We've partnered with Grand River Car Share so you can receive a free membership in the car share program and some driving credits. You can try out a new type of transportation or you can also get a discount on a new bicycle."

While the program has exceeded its goals, some say it hasn't done enough to protect the environment.

John Logel of Logel's Auto Parts says some scrap dealers are only interested in harvesting the steel. That's why he says its time to ensure all old vehicles are processed properly.

"It's amazing in 2011 with the amount of vehicles on the road, that we don't already have a mandate that only certain people can recycle cars."

Logel says he hopes the program and those like it are the government's first step in looking at how many vehicles are processed improperly.
