The show was originally scheduled to take place at the Capitol Theatre on April 17.
The 27-year-old singer, who first came to fame as a semi-finalist on American Idol in 2010 and is known for songs such as Dear No One (2013) and Should've Been Us (2015), posted on social media that all the remaining dates on her global Inspired by True Events tour have been cancelled.
She added: "I'm really bummed and this is the last thing I wanted to do, but it is necessary. Praying for our world right now! Please stay safe and look out for one another during these times and I'll hopefully see you soon."
It is the latest music event to be cancelled or postponed after the Ministry of Health put out an advisory to defer or cancel all ticketed cultural, sports and entertainment events that are expected to draw 250 participants or more.
Ticket buyers will receive full refunds through the original mode of payment to ticketing agency Sistic.
