The Canadian Shield is a collage of Archean plates and accreted juvenile arc terranes and sedimentary basins of the Proterozoic Eon that were progressively amalgamated during the interval 2.45–1.24 Ga, with the most substantial growth period occurring during the Trans-Hudson orogeny, between c. 1.90–1.80 Ga. [5] The Canadian Shield was the ...
Pukaskwa National Park in Ontario.. These hills support a large area of rich taiga forest dominated by black spruce (Picea mariana) along with jack pine and some paper birch (Betula papyrifera) and in the warmer south-facing areas some trembling aspen (Populus tremuloides), white spruce (Picea glauca), Ontario balsam poplar (Populus balsamifera) and balsam fir (Abies balsamea).
From decades of petrologic, geochronologic, and geochemical studies, it has become apparent that the Acasta Gneiss Complex, as it is now exposed in the Canadian Shield, is the result of the complex interplay between repeated periods of felsic magma generation from the partial melting of older, mafic crust, its crystallization as felsic plutonic ...
Georgian Bay has been known by several names. To the Ojibwe, it is known as "Spirit Lake".To the Huron-Wendat, it is known as Lake Attigouatan.

A second railway, the Canadian Northern (CNoR), was built across the northern portion of the park, opening in 1915. Both lines later became part of Canadian National Railway. The beginning of the end of rail service in the park happened in 1933 when a flood damaged an old Ottawa, Arnprior and Parry Sound Railway trestle on Cache Lake.
The Southern province is a narrow region from Sault Ste. Marie to Kirkland Lake, is made of rocks dating 1.8 to 2.4 billion years ago. [1] The Hudson Bay lowlands, located north of the Canadian Shield, are mainly made of sedimentary rocks from the Silurian Period, although some parts date from the Ordovician and Devonian periods.
