The railway was originally built between Eastern Canada and British Columbia between 1881 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling a promise extended to British Columbia when it entered Confederation in 1871.nder the initial contract with the Canadian government to build the railway, the CPR was granted 25 million acres (100,000 km 2). Proving already to be a very resourceful organization, Canadian Pacific began an intense campaign to bring immigrants to Canada.
The glenoid cavity or glenoid fossa of scapula is a part of the shoulder.
The scapula is also marked by a shallow, somewhat comma-shaped glenoid cavity , which articulates with the head of the humerus. The top end of the humerus consists of the head, the neck, the greater and lesser tubercles, and the shaft. The head is half-spherical in shape and projects into the glenoid cavity. The neck lies between the head and the greater and lesser tubercles. The greater and lesser tubercles are prominent landmarks on the humerus and serve as attachment sites for the rotator cuff muscles. There are four joints making up the 'shoulder joint': 1  The shoulder joint itself known as the Glenohumeral joint, (is a ball and socket articulation between the head of the humerus and the glenoid cavity of the scapula) 2  The acromioclavicular (AC) joint (where the clavicle meets the acromion of the scapula)
