3. Video investigated: Police in London, Ont. are investigating a disturbing case of animal abuse caught on camera.

4. Tragic fire: Sixteen horses were killed in a Toronto stable fire that officials called "tragic and sad."

5. Unusual cancer treatment: A Canadian researcher believes pairing high doses of erectile dysfunction medication with the flu shot might be a way to help the immune system naturally fight cancer after surgery.
