Toronto police are investigating a suspected arson at a GFL Environmental hauling yard near Cherry Beach.
Fire crews responded to the site on Unwin Avenue near Cherry Street around 1 a.m. on Thursday.
Officials say the fire has been extinguished and no injuries were reported.
There have a number of incidents at GFL yards in recent months.
In March, there were two shootings in less than a week at a site near Weston Road and Finch Avenue West. Back in February, there was also a fire at a GFL yard in Etobicoke.
Police have not said if these incidents are connected.
