Do what you can
If you’re in Ontario and are wondering what to with your old paint and batteries, you can find out where to take them on this website http://www.dowhatyoucan.ca/
“The new Ontario-wide Municipal Hazardous or Special Waste (MHSW) program will ensure that consumer products such as paint, solvents, used oil filters, single use batteries, antifreeze, propane tanks, fertilizers and pesticides are managed in an environmentally appropriate manner once consumers no longer need or want them.
That means less of these materials going to landfill sites. The target is to divert more than 33,000 tonnes of potentially hazardous or special waste in the first five years, up from the 16,000 tonnes currently collected.
The household hazardous or special materials you take to a collection location will be handled according to reuse and recycling priorities. We are setting up programs to reuse as much as we can. For example, paint can be reused. We’ll recycle as much as we can. And what’s left over, we’ll ensure is disposed of in an appropriate manner.  That’s good for the environment and its good for us.”
