"Dear Prime Minister Justin Trudeau, please repatriate your garbage: it stinks."
That's the message from activists in the Philippines and Canada as thousands of tonnes of malodorous household waste continue to rot away on Manila and Subic docks.
The pressure mounted this week when an array of Canadian and international environmental groups threw their support behind the EcoWaste Coalition of the Philippines, a local network leading the fight against foreign waste.
The campaign is the latest attempt to break years of deadlock over 77 remaining shipping containers full of reeking garbage that started arriving illicitly from Vancouver, British Columbia in 2013 - and have been decaying in shipyard limbo ever since.
"The dumping of Canadian waste in the Philippines is immoral and illegal," wrote Aileen Lucero, the national coordinator of EcoWaste, in an open letter to Trudeau on January 30.
"The scandal has dragged on for five years without resolution, despite promises from the Canadian government to address the problem, including public statements made by yourself as prime minister," she said.
A separate letter on Monday - also addressed to Trudeau - from groups including Greenpeace and the Canadian Environmental Law Association called on the administration in Ottawa to finally act and help solve a dispute that has soured its relations with Manila for years.
"Prime Minister Trudeau has promised that Canada will act in an environmentally responsible manner and fulfil its obligations under the Basel Convention, which forbids dumping waste overseas," wrote Kathleen Ruff, director of the human rights group RightOnCanada.
"Words are not enough," she said. "Environmentalists in Canada and around the world are calling on PM Trudeau to take action now to end this shameful misconduct."
The dumping scandal began in 2013 when 103 shipping containers filled with an estimated 2,500 tonnes of waste falsely marked as plastics for recycling started arriving from Canada.
The Philippine Bureau of Customs (BOC) soon found that the containers actually held "plastic bags, soiled papers, household garbage, and used adult diapers", and classified the waste as hazardous.
The Ontario-based company that shipped the containers from Canada has dismissed any claims of dumping, saying that the cost of shipping the waste to Southeast Asia would be much more than unloading it in Canada. It also pointed out in a report by the National Post that 2,500 tonnes is less than a day's worth of trash from Vancouver.
"I will not tolerate this matter sitting down," Leah Paquiz, a member of the House of Representatives, said at the time. "My motherland is not a garbage bin of Canada."
Other Philippine lawmakers were similarly outraged, a protest was held at the Canadian embassy, and 40,000 people signed an online petition denouncing Canada's actions.
Months later, according to the Rappler news website, the Department of Foreign Affairs asked the Canadian embassy to help repatriate the rubbish. The ambassador at the time said that the Canadian government had no authority bring back the trash, and pleas from Philippine officials soon ceased.
