Final answer:
Edmonton, the 5th largest city in Canada, is located in Alberta and is known for the largest shopping mall in North America and its significant natural resources, including tar sands.
Step-by-step explanation:
The country with Edmonton as its 5th largest city, situated on the North Saskatchewan River, in the province of Alberta, and being the site of the largest shopping mall in North America, is Canada. Edmonton is the capital city of the province of Alberta, and it is a significant cultural and economic center.
The region is known for its vast natural resources, especially in fossil fuel exploration. The area contains coal, oil, and natural gas, with oil being extracted from tar sands. These resources are of such abundance that projections suggest there is more oil in Canada's tar sands than in the underground reserves of Saudi Arabia.
The province of Alberta, where Edmonton is located, is also known for its fertile farmland which contributes to Canada's grain and beef operations, thereby playing a crucial role in the country's agricultural sector.
