There is no such thing as untouched forest in Canada.
A forest is a living community of organisms that naturally experiences constant change. Over time, forests experience many disturbances (including fire, insects, disease, drought, wind throw, floods and timber harvesting), yet trees continue to grow back naturally. In the forest, nothing is ever static. This is particularly true in the boreal forest, which is ecologically adapted to renew itself through disturbances such as fire.

Although many forests are in remote areas, inaccessible to people, human activities such as harvesting do affect other forests. However, modern methods of harvesting trees are often intended to mimic natural disturbances and harvested areas are regrown. Canada’s managed forests will generally grow for 60 to 100 years between harvests, so most managed forest areas return to a natural state for considerable lengths of time.
