Holding up work at job sites across Toronto, dozens of dump truck drivers are participating in a demonstration aimed at bringing attention to their concerns about pay and road safety.

More than 150 striking owner-operators parked their trucks at the corner of Dixie and Derry roads in Mississauga on Tuesday morning.

The drivers, who are part of the Ontario Dump Truck Association, are hired by construction and excavation companies.

Drivers taking part in the protest told CP24's Cam Woolley that their employers are illegally overloading their trucks, causing damage to vehicles, and threatening road safety.

They told CP24 the companies reimburse the cost of any fines, but demerit points handed out for offences are hurting drivers' records.

Demerit points result in higher insurance fees, and can lead to possible sanctions or suspensions from the Ministry of Transportation.

Drivers are also requesting higher pay, telling media they haven’t seen an increase in four years, despite increased fuel, licensing, insurance and maintenance costs.
