Other notable cities include Prince Albert , Moose Jaw , Yorkton , Swift Current , North Battleford , and the border city Lloydminster -LRB- partially within Alberta -RRB- .   Saskatchewan is a landlocked province with large distances to moderating bodies of waters . As a result , its climate is extremely continental , rendering severe winters throughout the province . Southern areas have very warm or hot summers . Midale and Yellow Grass near the U.S. border are tied for the highest ever recorded temperatures in Canada with 45 C observed at both locations on July 5 , 1937 . In winter , temperatures below -45 C are possible even in the south during extreme cold snaps .   Saskatchewan has been inhabited for thousands of years by various indigenous groups , and first explored by Europeans in 1690 and settled in 1774 . It became a province in 1905 , carved out from the vast North-West Territories , which had until then included most of the Canadian Prairies . In the early 20th century the province became known as a stronghold for Canadian social democracy ; North America 's first social-democratic government was elected in 1944 . The province 's economy is based on agriculture , mining , and energy . Saskatchewan 's current premier is Brad Wall and its lieutenant-governor is Vaughn Solomon Schofield .   In 1992 , the federal and provincial governments signed a historic land claim agreement with First Nations in Saskatchewan . The First Nations received compensation and were permitted to buy land on the open market for the tribes ; they have acquired about 3079 km2 , now reserve lands . Some First Nations have used their settlement to invest in urban areas , including Saskatoon .
