Following a price bump in April, Saskatchewan has the highest year-to-year inflation rate of any Canadian province.

According to the Statistic Canada's monthly inflation report released on Friday, consumer prices in Saskatchewan rose 1.5 per cent from May 2014 to May 2015.

It would have been lower, except that the consumer price index increased 1.2 per cent in April alone.

StatsCan says prices in Saskatchewan for natural gas remained higher than a year ago, while every other province posted year-over-year declines.

Another source of higher prices was cars and trucks. Saskatchewan recorded a 3.4 per cent rise in prices for the purchase of passenger vehicles.

On the other hand, the report says the province's gasoline index decreased more than the national average on a year-over-year basis.
