The previous high for a single month was 82 in January 2016.
The synthetic narcotic, fentanyl, has been largely to blame for the carnage, with 60 per cent of the deaths between January and October in the province linked to the powerful drug.
Chief Coroner Lisa Lapointe announced Monday that 755 people have died in B.C. of an illicit drug overdose between January and November, a 70 per cent increase over the same period past year.
Police said an additional nine people died in the city last Thursday night, one of many troubling statistics that has Lapointe warning that December "is looking like a very bad month".
The B.C. minister of public safety and solicitor general released a statement in response to the November numbers. "We must redouble our efforts, because behind each of those numbers is a person with friends and family who are forever impacted". Three of those new sites, which essentially operate like Vancouver's supervised-injection facility, Insite, have already opened in Vancouver.
The province's latest move was to announce plans for overdose-prevention sites in Vancouver, Victoria, Surrey and Prince George where people can inject illicit drugs while monitored by trained professionals equipped with naloxone, which reverses the effects of opioid overdoses.
Most of the deaths took place on Saturday or Sunday.
Fentanyl remains present in a high number of those deaths. That's up from 510 during all of a year ago, 366 in 2014, 330 in 2013, 273 in 2012, and 292 in 2011.
The new statistics bring the total number of illicit drug deaths for the year to 755, an increase of 70.4 per cent over the same period last year.
The number of British Columbians dying from fentanyl-related overdoses increased by almost 200% in 2016.
