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.

Why is the Canadian shield also known as the precambrian shield?
The Canadian Shield is known as the Precambrian Shield because it is made up of some of the oldest rock formations on Earth, dating back to the Precambrian Eon. These rocks were largely formed between 4.6 billion to 540 million years ago, before the Paleozoic era began.

What part of Canada was created during the Precambrian era?
The Canadian Shield, which covers around half of Canada's landmass, was created during the Precambrian era. It is one of the oldest geological formations on Earth, characterized by its ancient rocks and diverse mineral resources.
What was the Canadian shield by?
Canadian Shield was formed when 2 tectonics plates collided, when they collided, folding occurred. The plate that was forced down, melted and rose back to the surface to cool down over time. These rocks (that were cooled down) eventually came to be known as the Canadian Shield.

Which era does the rock of the Canadian Shield date back to?
The rock of the Canadian Shield primarily dates back to the Precambrian era, specifically the Archean and Proterozoic eons. This geological formation is among the oldest in North America, with some rocks estimated to be over 4 billion years old. The Shield is characterized by its ancient crystalline basement rocks, which have been shaped by tectonic processes and erosion over billions of years.
