Cool, damp weather over the last week slowed harvest operations in some areas of the province.
In addition, many producers also reporting frost, and a hard frost - which is described as below -2 celcius for at least four straight hours.
Crops Extension Specialist Matt Struthers says while a number of areas reported frost it shouldn't do much damage now with crops beings so far advanced.
The rains may have caused some bleaching and minor downgrading to standing or swathed cereal crops.
This week's crop report shows harvest operations are now 73 per cent complete in the province, up from 64 per cent last week.
Harvest is most advanced in the southwest where 96 per cent of the crop is in, other than some canola and flax which is still left to harvest.
