An award-winning playwright and theatre actor, Rinaldi has collaborated as a writer and actor on countless theatre productions throughout Canada and is co-founder of the darkly comedic comedy troupe, Theatre Melee. She began performing at the age of six in National Film Board films and in local school productions. Fortunate enough to count Canadian filmmaker Anne Wheeler as a neighbour, Rinaldi had the opportunity to audition for a part in her film The War Between Us while still in high school. After booking the lead and spending two months on location in New Denver, B.C., Rinaldi knew she wanted to pursue a career as an actor and enrolled in the prestigious Theatre Training program Studio 58 in Vancouver and graduated with Honours. 

Rinaldi has appeared in such television productions as CBC's HOW TO BUY A BABY, Girl in the Bunker, Degrassi: The Next Generation, The Killing, Arrow, Supernatural, Fringe, Robson Arms, These Arms of Mine and Psych. Her feature film credits include Life, Jennifers Body, The Tooth Fairy, The War Between Us and The Linda McCartney Story. 

Recent credits include the new HULU series Holly Hobbie, and Wayne, a new series from the writers of Deadpool for Amazon. In the fall of 2018, Rinaldi completed the short film Dove, which she wrote, directed and in which she starred. 

Rinaldi and her business partner, film actor Shaun Smyth, opened the Hamilton Film Centre last year. The school is designed to teach acting for the camera for all ages.
