The Honda plant in Alliston has extended its shift reductions until May 6th.
The cut in hours at the Alliston plant was originally expected to last until the 15th of April, as the carmaker deals with a shortage of parts coming from Japan after the devastating earthquake and tsunami.
Honda spokesperson Lori Van Valkenburg says the daily production adjustments vary.
She says some shifts are working four hours a day, others, six hours a day.
She says all the associates are being provided with the opportunity to work, and some workers will do other things such as training.
