Thank you, Mr. Chair.
Dr. Quinney, I'm going to begin with you. The estimated damage for invasive species worldwide is thought to be about 5% of the global economy, and both of you picked up on earlier the $13 billion to $35 billion for 16 species. Dr. Quinney, has there ever been a comprehensive study that's looked at the invasive species in Canada and what the economic impacts have been, or is there just this one study?
