Why do you think a lumberjack's life is full of hardships?
Show SolutionHide Solution↓
A lumberjack leads an isolated life which is full of hardships.
- They set out in autumn to live in temporary wooden houses, or shanties, with steep roofs. Sometimes, constructing a house becomes a problem due to permanent frost on the ground.
- Therefore, in summer, the lumberjacks build many kilometres of rough track roads deep into the forest. This track leads to the lumber camps, which consist of a few buildings with a kitchen, a dining room and a bedroom.
- The climate is extremely cold, especially in winter, making outdoor work very difficult.
- They have to cut down large trees using heavy tools and machinery, which is physically exhausting.
- In the past, lumberjacks returned home walking many kilometres after several months of stiff work in the forest.

What changes have occurred in the life of the lumberjacks in recent years?
Show SolutionHide Solution↓
In the earlier days, lumberjacks used to live in lumber camps, which consist of a few buildings with a kitchen, a dining room and a bedroom. Earlier, their houses used to be crudely built log cabins, but today, they are more comfortable. Most of the lumberjacks now live in settled communities.
The life of the Canadian lumberjacks is on the way to modernisation. Following the introduction of a wide range of modern scientific tools and new techniques of lumbering, the task of the lumberjacks has become much easier than that of their predecessors. Many lumberjacks earn huge amount of money after working for several years in the log farms. They are called lumber barons. Some of the richest people in Canada today are the lumber barons. They enjoy a very high standard of living.
