Carla Bosacki was a presence on Global Toronto's weekend weather for years, as well as filling in for meteorologists Anthony Farnell and Ross Hull when needed. But her future forecast has changed, leaving the network after many years to work for a public relations firm. She'd been with Global in a variety of roles for almost 16 years. 

Mike Arsenault has replaced her on the Saturday and Sunday show as a "weather specialist," but it's not known if he's in that position permanently.
