The Canadian Shield, one of the world’s largest geologic continental shields, centred on Hudson Bay and extending for 8 million square km (3 million square miles) over eastern, central, and northwestern Canada from the Great Lakes to the Canadian Arctic and into Greenland, with small extensions into northern Minnesota, Wisconsin, Michigan, and New York, U.S. The Canadian Shield constitutes the largest mass of exposed Precambrian rock on the face of Earth. The region, as a whole, is composed of ancient crystalline rocks whose complex structure attests to a long history of uplift and depression, mountain building (orogeny), and erosion. Some of the ancient mountain ranges can still be recognized as a ridge or belt of hills, but the present appearance of the physical landscape of the Canadian Shield is not so much a result of the folding and faulting and compression of the rocks millions of years ago as it is the work of ice in relatively recent geologic time. During the Pleistocene Epoch (2.6 million to 11,700 years ago), the vast continental glaciers that covered northern North America had this region as a centre. The ice, in moving to the south, scraped the land bare of its overlying mantle of weathered rock. Some of this material was deposited on the shield when the ice melted, but the bulk of it was carried southward to be deposited south and southwest of the Canadian Shield. The resulting surface consists of rocky, ice-smoothed hills with an average relief of 30 metres (100 feet), together with irregular basins, which are mostly filled by lakes or swamps. In places the old mountain ranges may be recognized by hills several hundreds of meters in height. The northeastern portion, however, became tilted up so that, in northern Labrador and Baffin Island, the land rises to more than 1,500 metres (5,000 feet) above sea level. :)

Religious tolerance in the current scenario is discussed below in details.
Explanation:
Religious toleration is citizens supporting other citizens to meditate or exercise other religions and faiths.
In a country with a state religion for example Arab countries where the state religion is Islam, toleration indicates that the government supports other religions to be there. Many nations in past centuries permitted other religions but only in isolation. This has become rare nowadays, religious toleration especially in Islam following states become very rare.
