What was the impact of glaciers on the Canadian shield?
Although the exact amount of material transported will never be known, suffice it to say that massive amounts of soil and rock were carried away from the area of the Canadian Shield by glaciation during the most recent ice-age. The weight of the glaciers actually depressed the land surface, and scraping and gouging by rock-filled ice created thousand of depressions which are now lake basins.

What part of the earth was formed during the Precambrian Era?
50% of Canada was created during this era. This part is called Canadian Shield.
What was the most dominant era for the Canadian Shield?
It was welded together between 1.9 and 1.8 billion years ago in the Trans-Hudson orogeny during the Paleoproterozoic. The final structure of the North American craton has persisted now for at least 600 million years. Most of the overlying buildup of loose rock and soil was later removed by glaciers during successive ice ages.
