Happy hump day! It’s Wednesday, and CTV News’ 5 things brings you the top stories you need to know: Assembly of First Nations Chief Perry Bellegarde will outline the AFN’s priorities in the upcoming election; a new study on autism from researchers in Toronto has found which two tests may help diagnose autism; Canada may have slipped into a “technical recession” but there are some reasons to remain optimistic; Ontario police are appealing for new leads 25 years after a teen’s murder; and a Vancouver model is speaking out about a now-defunct Facebook page that focused on body shaming.

1. Aboriginal election issues: Assembly of First Nations National Chief Perry Bellegarde will outline in Ottawa today the AFN's priorities for the upcoming federal election. Bellegarde has been vocal in urging First Nations people to get out and vote, saying there are 51 ridings across the country where aboriginal voters could sway the vote if enough of them go to the polls.

2. Autism study: Doctors have traditionally relied on various standardized tests -- including observation of how a child learns -- to make an autism spectrum disorder diagnosis. But a new study published by researchers from Toronto's Hospital for Sick Children found that the use of two diagnostic tests together may better help identify the genetic mutations potentially linked to ASD.

3. Make mine mild: Canada’s economy has met the criteria for a “technical” recession, but it’s not as bad as it sounds: many of the country’s larger financial indicators are still positive. Here are four reasons why analysts feel Canadians should remain optimistic about the current state of the economy.

4. Public appeal: Ontario Provincial Police are asking the public for help in solving a 25-year-old murder. Leah Sousa, 13, was sexually assaulted and killed in Cumberland Beach on Sept. 1, 1990 by an intruder. The resulting case file is one of the largest in OPP investigative history and now police are asking for any fresh tips or witnesses to come forward.

5. No need for Photoshop: A plus-sized Vancouver model is speaking out after her picture was picked up by a body-shaming Facebook paged called project Harpoon. Ruby Roxx says she was surprised and angered when she found the heavily edited photographs of herself on the now defunct page.
