Bhante Jinaratana was born in Toronto, Canada. He became interested in meditation as a student at the University of Toronto, and began attending intensive retreats in 2002. After graduating with an H.B.Sc. (neuroscience, mathematics) in 2004, he taught English for a year in Nanning, P.R.C. Desiring to ordain, but without knowing a suitable place to do so, he travelled to Brisbane Australia and completed a Graduate Diploma in Education in 2008 at the Queensland University of Technology. During that time he had the opportunity to stay for an extended period at Dhammagiri Forest Hermitage as eight-precept meditator. The guidance he received there helped him to gain the confidence to finally ordain.
Bhante Jinaratana received novice ordination at Na Uyana Forest Monastery in Sri Lanka in July 2011, and higher ordination in June 2012. Most Venerable Na Uyane Ariyadhamma Mahāthera was the preceptor for both ceremonies. From 2019-2021 he stayed at Pa Auk Monastery, Pyin Oo Lwin Myanmar, meditating under the guidance of Sayadaw U Kumārabhivaṃsa and Most Venerable Pa Auk Sayadaw Āciṇṇa.
