OTTAWA — More than 27,000 kilograms of used medical needles were safely returned to pharmacies across northern Ontario in 2025. However, environmental and waste management officials warn that a dangerous volume of biohazardous sharps is still being tossed into household trash and recycling streams, leaving front-line workers exposed to puncture injuries and blood-borne infections.
Data from recent waste audits conducted by Circular Materials reveals that used medical sharps are consistently showing up in curbside recycling bins, appearing in approximately 0.4 per cent of Ontario’s blue box samples.
“While that number might seem small, any presence of sharps in the recycling stream creates a real direct risk of injury and hazardous material exposure for our workers,” said Allen Langdon of Circular Materials. He noted that manual sorters at consolidation and recycling facilities are at the highest risk, as needles are often buried beneath layers of paper and plastic, leading to accidental punctures when workers reach into the sorting lines.
The problem is hitting local municipalities hard. In Greater Sudbury alone, waste management services have identified a watchlist of roughly 316 households that frequently improperly dispose of medical sharps in their regular trash or blue boxes.
Renee Brownlee, from environmental services at the City of Greater Sudbury, stressed that these needles are showing up at recycling centers, sorting belts, and landfills. While the city operates a household hazardous waste depot and a “toxic taxi” service, officials strongly urge the public to utilize the free pharmacy take-back program funded by the pharmaceutical industry.
“The number one thing we want to encourage people to do is to use that service,” Brownlee said. “We do continue to accept them at our household hazardous waste depot, but then that’s a cost to the city and therefore a cost to the taxpayer.”
Rachelle Rocha, a pharmacist at Seasons Pharmacy & Culinaria, explained that the pharmacy return program ensures that consumer medical waste is safely contained and properly incinerated. “If you have a needle stick injury, you never know where that needle has been, and now you’re at risk of all kinds of problems—HIV and hepatitis being the most impactful ones,” Rocha warned.
The physical and psychological toll on affected workers is significant. Due to changes in hospital medical protocols, workers who suffer a needle stick injury are no longer automatically given immediate preventative medications; instead, they are required to undergo rigorous medical self-monitoring for up to six months, causing prolonged psychological distress.
The volume of medical sharps requiring disposal is expected to climb dramatically. While home-use needles have traditionally been driven by diabetes and cancer treatments, the exploding popularity of GLP-1 medications—such as Ozempic and Wegovy—has led to a surge in single-use needles. An estimated 3 million Canadians currently use GLP-1 medications at home.
To combat the issue, participating pharmacies are distributing free, puncture-proof sharps disposal containers equipped with QR codes that guide users to their nearest designated drop-off location. Officials emphasize that resolving the crisis ultimately relies on public education and breaking the habit of throwing medical waste into household bins.
