A hazardous materials situation closed several roads in the Thamesford area overnight and resulted in two homes being evacuated.
The provincial police were called to the area just after 7:30 p.m. Thursday for a truck that was leaking hazardous materials into the ditch along Road 68.
Several crews, including a hazmat team from the London Fire Department were called in to assist with the clean-up.
Police say two homes in the area were also evacuated as a precaution.
Fire officials on scene say that Thursday evening a truck driver pulled over when he felt his load shift, upon inspecting the trailer he could smell chemicals, noticed a haze and called authorities.
Officials say the spill - a form of concentrated bleach - was contained to a 30-metre stretch of the ditch.
A Hamilton-based environmental clean-up company has been called in to deal with the spill.
Several roads remained closed for much of Friday, including Road 68 between Highway 119 and 31st Line, 21st Line between Road 68 and Road 66, 25th Line between Road 68 and Road 66 and 23rd Line between Road 68 and Road 74.
Some closures are expected to continue until the clean-up is complete.
No injuries were reported in the incident.
