Police have confirmed that a 20-year-old Ottawa woman who remains hospitalized after ingesting pills over the Canada Day weekend had taken MDMA - more commonly known as Ecstasy.

Toxicology testing continues on a 19-year-old Montreal woman, who died hours after arriving at a local hospital after also ingesting pills. Police said it could take up to three months for the results.

An investigation was launched after the two separate incidents in central and east Ottawa, which the Sun learned were both part of the Escapade Music Festival.

There is nothing to suggest foul play in connection with either incident. The incidents are not believed to be connected.

Escapade organizers earlier told the Sun they were unaware of any major incidents at their event.

MDMA, or methylenedioxymethamphetamine, is a synthetic drug that can be produced in clandestine labs. Ecstasy is the street name for drugs that can include MDMA.

The drug can cause body temperature to ramp up, which can be fatal for those who take it at high-energy, overheated dance parties, according to the RCMP.
