Keeping Canada’s Most Urbanized Watershed Clean

Second Annual “Cleanup the Don” a success

On May 5th, 2019, more than 100 dedicated volunteers grabbed bags to participate in the University of Toronto’s Trash Team’s 2nd Annual Cleanup the Don, a collaboration with the Toronto Region Conservation Authority (TRCA) and Ocean Conservancy’s International Coastal Cleanup (ICC) coordinator in Canada, the Great Canadian Shoreline Cleanup. In conjunction with the TRCA’s annual Paddle the Don event, Cleanup the Don brought members of the community down to the Don River to traverse and conserve one of Toronto’s most important watersheds.

Stretching nearly 24 miles and spanning more than 88,000 acres, the Don River is one of the largest rivers entering Lake Ontario. The Don River Valley is a popular area for recreational activities, including biking, running, fishing and canoeing. The area is also home to a wide variety of wildlife, including some endangered species like the Redside dace fish and American chestnut tree.

Habitat loss and chemical pollution are major threats to urbanized watersheds like the Don River. Estimates from our most recent University of Toronto Trash Team survey of the river suggest it is also an important route for hundreds of pounds of plastic litter from urbanized areas (like the Greater Toronto Area) to enter the Great Lakes every year.

This year for Cleanup the Don, 107 volunteers spread out across five sites from E.T. Seton Park to Corktown Commons, a six-mile stretch. In all, we removed approximately 550 pounds of plastic litter from the shorelines.

The top six trash items closely tracked what volunteers find during the ICC every year, including cigarette butts (25%), plastic food wrappers (13%), plastic bags and other single-use plastics. We were also surprised to find some unusual items, including a tent and VHS tape cover.

A selection of litter collected during this cleanup was also used to create a mural depicting the Don River Valley. Repurposing litter into artwork can be a great way to raise awareness about how plastic pollution affects your local environment.

Since most plastic pollution comes from land-based sources, understanding the sources of plastics in the environment can help us “turn off the tap” or stop the flow of plastics to local waterways like the Don River. Single-use plastic restrictions (such as plastic bag bans) and improvements in waste management can help reduce the number of these items that end up in the environment. Below are five simple actions that individuals can make to help keep plastic from entering the Don River watershed and other waterways:

  1. Reduce your use of single-use plastics! Opt for more eco-friendly alternatives like reusable shopping bags and metal/glass straws.
  2. Clean up your local watershed. Join a local cleanup or start your own. Join Ocean Conservancy on the world’s largest single-day volunteer effort on behalf of the ocean, the International Coastal Cleanup. This year it’s September 21st, 2019. Tips on how to organize a cleanup in your area are available through the Great Canadian Shoreline Cleanup website.
  3. Know your bins! Be aware of which items go in green, black and blue bins. For guidance in the City of Toronto, check out the Waste Wizard app!
  4. Support legislative or community action to reduce single-use plastics and improve waste management in your area.
  5. Educate friends and family about the plastic pollution problem.

Discovering the East Don

Cool temperatures didn’t stop our team from keeping rivers clean

On November 10 our team joined Toronto Region Conservation Authority (TRCA) to clean a portion of the East Don Trail in Charles Sauriol Conservation Area. You might not think of organizing a cleanup in November, but litter season is year-round so it was important for our team to head to a local shoreline in the city to make a difference. It was a chillier cleanup than usual however the results indicated trends we are all too familiar with, single-use items scattered on the shoreline, many of them plastic.

Our team of 20 were eager to get out there and see what type of items we could remove, and we were amazed at the quantity of what we found. Our team also filled out a brand audit to uncover not only what items were most commonly found as litter, but (when identifiable), which brands came across.

A total 138 lb of litter was removed, and our top 10 items included a selection of single-use plastic items we see at many shorelines in the city, including cigarette butts and many items such as bags, bottles and food wrappers. Coffee cups were also found during the cleanup, which might not sound like a plastic material, but due to their lining of polyethylene we consider them as such. This lining means coffee cups are a challenging item to recycle and instead should swapped for reusable alternatives, like a stylish travel mug!

Cleanup The Don

Making Toronto’s most urban river trash-free

On May 6th, 2018, we led our first annual Cleanup the Don inland coastal cleanup to remove trash along the Don River, keep trash out of Lake Ontario and raise awareness about the issue of plastic pollution. Students and researchers from the University of Toronto joined forces with the Great Canadian Shoreline Cleanup, the International Coastal Cleanup and Paddle the Don, an annual event organized by the Toronto and Region Conservation Authority (TRCA) where local residents can canoe and kayak down the Don River.

The Don River is Toronto’s most urbanized watershed and is widely enjoyed by citizens and tourists alike. On any given day, one can see a wide variety of activities in the expanse of parkland in the ravines around the Don River. Cyclistswalkers, runners, anglers and others use the trails alongside the river, which is located a short walk from Toronto’s downtown core. But, it is also a river with plastic pollution throughout.

At six locations, spanning over 10km of the Don River, teams collected 210 kg of trash, nearly half of which was recycled. Volunteers found many common items such as plastic packaging, coffee cups, plastic bottles and plastic bags. However, we were surprised to find a few unusual items like a vacuum cleaner, a toboggan and Venetian blinds! By number, cigarette butts were the most common item collected during the cleanup, and nearly 2000 were sent to be recycled. Despite their small size, they can be particularly harmful in the environment due to the toxic chemicals they contain.

Scientists estimate that between 4.8 to 12.7 million metric tons of plastic enter the ocean from land every year due to mismanaged waste. Plastic can also enter the environment as microplastic—small plastic less than 5mm in size. Canada is taking steps through the microbead ban, which will eliminate microbeads in personal care products (like toothpaste and facewash) as of July 1, 2018. However, policy does not yet address other sources of microplastics, such as microfibers that shed from textiles or synthetic rubber dust from tires.While some pollution may originate from park-goers, wind and rain also carry plastic debris from land into rivers, lakes and oceans. And piece by piece, the pollution adds up.

This year Canada holds the presidency of the G7. As part of its efforts to protect our oceans, Canada has indicated its intentions to support international policy for a zero-plastics-waste charter. At the national level, Canadians have recognized work is also needed to address single-use plastic, increase recycled content in plastic products, and to increase the national recycling rate.

There are many ways we are working to tackle the plastic pollution problem, and we encourage others to do the same:

  1. Avoid single-use plastic items: Using environmentally-friendly items such as stainless steel or glass straws and reusable water bottles, shopping bags and utensils, can help divert waste from landfills and the environment.
  2. Improve recycling at home: By learning better recycling habits, we can prevent recyclable products from ending up in a landfill. While the list of “recyclables” varies depending on where you live, there are often resources available to help. Where we live, the City of Toronto’s Waste Wizard identifies the proper bin to put your waste.
  3. Get involved in your community: Joining a cleanup in your area, (or leading one!) can help reduce plastic in the environment. The Great Canadian Shoreline Cleanup and International Coastal Cleanup have resources to help organize cleanups, as well as track and report data.

As we continue to lead cleanups, we are hoping to gain valuable information to answer questions such as: Do patterns of waste change over time? Will accumulation of litter in the Don River decrease as “waste literacy” in this watershed improves? We also hope that the data we collect can help provide a better estimation of plastic sources and increase scientific knowledge to inform effective policies to prevent further plastic pollution.

There is still a long way ahead to achieve zero-plastic-waste in our city and others, but our first cleanup showed us that the people care about the plastics problem and are willing to help. Over the next year, we have exciting plans to reduce waste entering Lake Ontario and increase waste literacy in our city. We look forward to seeing you out there!
