It was over the weekend, when York Regional Police investigated two seperate shootings...both happening at short term rentals.
And police told us that makes it tough to find the people who were responsible.
One shooting happened in Markham, where no one was hurt, but the other sent two people to hospital in Vaughan.
So what's being done to clamp down on these "party places on demand?"
"We've been proactive in the city of Markham," says Mayor Frank Scarpitti. "We basically came to the conclusion to prohibit short term rentals in the city."
He says many of the places weren't being used by travellers, but by partiers instead.
"A lot of them were being used for party houses and causing disturbances in stable neighbourhoods." says Scarpitti.
If neighbours suspect a home is being used as a short term rental, they can call bylaw officers to have it shut down.
Vaughan, where the other shooting happened, is working on regulating the industry as well.
"The City is taking action to regulate short-term rental housing, such as Airbnb and Expedia, through developing the necessary regulations that will establish controls measures, inspection powers and penalty framework and will identify any home in Vaughan that provides short-term accommodations." says a city spokesperson in a statement.
We checked in with AirBnB as well, to find out what they were doing about escalating violence.
The senseless violence reported is abhorrent and has no place in the Airbnb community, and our thoughts are with those who have been impacted by these unfortunate events." said a spokesperson in a statement. "We have removed the booking guests from our platform and are in touch with York Regional Police to offer our support in their investigation."
But they went on to point out that, "hosting is a big responsibility and we encourage all hosts to outline clear rules regarding minimum night stays, noise, parties and events so that prospective guests have this information at the ready prior to booking."
