Ontario spends more than $50 million per year fighting invasive species. Here are some of the worst offenders

Invasive species, including plants, animals, insects, fish and pathogens living outside their native range, can cause flooding, reduce climate resiliency and decimate Ontario's native species.

Researchers find evidence of Nunavut's 1st invasive barnacle through its poo

Researchers say they've found evidence of the first invasive barnacle species in Nunavut's waters - a discovery they believe is a result of climate change. Samuel Wat has that story.
