Olivia captioned the photo with a butterfly emoji and wrote: "Way back in The 6ix."
It seems the actress was referencing the nickname rapper Drake coined for his hometown of Toronto.
Olivia, who played Raffy Morrison on the popular Aussie soap before leaving the role earlier this year, has been in the Canadian city to film the new Disney flick Secret Society of Second Born Royals.
Olivia recently opened up to New Idea about her love life, while walking the red carpet for The Lion King premiere in Sydney.
The actress exclusively told New Idea that she had split from her Australian model boyfriend, Ethan Hay.
"Whatever happens, happens - there's a lot of beautiful people out there!" she said of potential future romances.
