The RCMP have confirmed to Newstalk1010 that the Ottawa Paramedic Services attended 24 Sussex Drive on the weekend.
Reports indicate a young woman was taken from the official residence of the Prime Minister, and may have been suffering from alcohol poisoning.
A spokesperson for the RCMP says "This was a medical call and not a police matter. It did not involve any of our protectees."
Reports indicate that Prime Minister Harper's son, Ben turned 18 on the weekend and was celebrating at the house.
It's unclear as to if the PM or his wife was home at the time.
Legal drinking age in Ontario is 19, but just across the border from Ottawa in Gatineau, the drinking age is a year younger at 18.
The Prime Minister's Office responded to a request for information only with "we have nothing to add to your story."
