Niagara Regional Police say they laid 528 impaired driving charges in 2017.

Of those charges, 43 per cent were laid between 12 a.m. and 6 a.m., and 39 per cent were laid between 6 p.m. and 12 a.m.

The most arrests were made on weekends, with around 140 arrests on Saturdays and around 115 arrests on Sundays.

The months of December, July and August saw the highest rates of charges laid.

A charge is not a criminal conviction.

The Niagara Regional Police starting naming and shaming alleged impaired drivers in 2015.

Since then, many media outlets have decided against publishing the names of alleged impaired drivers as a matter of principled reporting, since resources cannot be devoted to follow each case to the end.

Not every driver charged with impaired driving will be convicted of a criminal offence.
