Thanks for the question.
We made changes to our regulations to require that, should a waste not be accepted in the receiving country, it's the responsibility of the waste exporter to manage the return of the waste to Canada.
With respect to the specifics on the waste containers that were exported to the Philippines, between 2013 and 2014 a Canadian company exported containers labelled as recycled plastics to the Philippines. While the export of the material at issue was not at the time regulated under Canadian law, it was exported. Then it was subsequently refused entry.
