Winnipeg police are issuing yet another alert about the deadly drug fentanyl after a toddler was rushed to hospital Tuesday.

The child was taken to hospital on Oct. 18 following concerns about the presence of what investigators suspect may have been fentanyl residue in the child's home.

The toddler, under a year-and-a-half in age, was taken to hospital in critical condition but has since been upgraded to stable.

Winnipeg police said the Clandestine Lab Team responded to a home on Aikins Street at around 5:30 p.m.

Const. Rob Carver said police can't confirm fentanyl was the reason the child was taken to hospital.

"We don't know for sure yet if what we suspect was fentanyl," Carver said.

Police will have to wait for the results of tests on the substance which will be conducted by Health Canada.

Investigators said there was no evidence a clandestine drug lab was in operations.

Police said their investigation into the incident is ongoing.

"If we have an infant who was exposed to a potentially deadly substance, an illegal substance then investigators may be looking at the possibility of child endangerment charges," Carver said. "I think the message is for anyone who may be choosing to use fentanyl, they need to know that their choice may result in someone else's death."

Meantime, the mother of a Winnipeg woman who died of a drug overdose this month wants to warn other parents about the dangers of fentanyl.

Cynthia Genaille’s daughter Brittany Genaille died Oct. 6 in her home.

Genaille suspects Brittany may have used the potent drug fentanyl thinking it was methamphetamine.

Winnipeg police confirmed their officers as well as the Winnipeg Fire Paramedic Service responded to the home for a sudden death call.

Genaille worries about the increasing presence of fentanyl on Winnipeg streets.

The Chief Medical Examiner’s Office has been tracking fentanyl deaths for a number of years.

Acting Chief Medical Examiner Dr. John Younes said there was a modest increase between 2013 and 2015.

Dr. Younes said fentanyl was either the primary or contributing cause of 20 deaths in 2015. There were 12 fentanyl-related deaths in 2014, and 10 in 2013.

Numbers for 2016 aren’t available yet, but Younes expects another increase.

“There’s definitely an upward trend,” Younes said. “Not a meteoric rise like British Columbia or Alberta.”

Dr. Younes said the Chief Medical Examiner’s Office is currently working on developing new protocols to detect carfentanil during toxicology tests.

Carfentanil is not intended for humans, and because of that Dr. Younes said it was not something drug labs routinely screened for during autopsies.
