Police spent overnight Thursday guarding a Hintonburg naturopathic clinic after the death of a 51-year-old woman.

The Sun learned the woman died in hospital on Thursday, shortly after receiving some type of IV treatment at the Ottawa Integrative Cancer Centre along Bayswater Ave.

Emergency crews were called to the centre at about 3 p.m. for a woman with trouble breathing.

Police had been guarding the centre since Thursday evening and into Friday morning, when it remained shut down.

It re-opened later.

Police said they were there at the request of the coroner, to guard the scene.

Major crime detectives had been consulted in connection with the incident.

Police released the scene around noon on Friday and said it appeared to not be a suspicious death for them to investigate.

Autopsy results are pending.

The centre bills itself as "the ﻿first integrative cancer care and research centre of its kind in Eastern Canada," and offers "complementary support" alongside conventional treatment, such as naturopathic oncology and acupuncture.

Naturopathy is not regulated under the Ontario College of Physicians and Surgeons, but they said similar legislation is in the process for it, under a different overseeing body.

The OICC employs regulated healthcare practicioners, according to their wesbite, and is a not-for-profit regional centre of the Canadian College of Naturopathic Medicine.

The OICC and the CCNM were not immediately available for comment.
