In northern Alberta there is occasional air transport connecting Peace River and Fort Smith, N.W.T. At the same time this route also serves the centres of Carcajou, Fort Vermilion, and Keg River. Air transport companies maintain passenger, mail, and express schedules to all airfields and seaplane bases described above. Large modern aeroplanes, making several flights each week, are used on the air routes from Vancouver and Edmonton to Whitehorse and Fairbanks, and also on the Edmonton to Yellowknife route. On some of the other toutes schedules vary from summer to winter and with the amount of trafic, but weekly, semimonthly, or monthly service is usually available to the various fields. On these latter, less frequented lines, single-engined planes equipped with floats or skis are still used. In addition to the flights for which schedules may be obtained from the commercial companies, charter trips can be provided to any airfield, seaplane base, lake, or river on which pontoon or ski equipped aircraft can land. ‘As a result of this network of airfields, served by a variety of planes, a rapid transportation system has been built up through the length and breadth of the whole of northwestern Canada. During war time this service was limited only by the equipment available. Not only have existing airfields now been enlarged and new airfields built, but communication facilities, either telephone, telegraph, or radio, and weather reporting stations and services have been extended throughout the whole region. CONCLUSIONS Northwestern Canada, with its innumerable lakes and rivers, great distances between settlements, and slow water transportation during a shert ice-free season, is peculiarly suited to the use of aeroplanes. It is doubtful if few other parts of the world have developed air service to as great an extent in opening up the exploration and resources of the country. In northern Canada aeroplanes are used as a common vehicle of all-season transport and not as a com petitive means of luxury travel. High speed, although an advantage, is not essentially the prime factor in the develop- ment of northern air transport, for guaranteed, reasonably fast schedules with a low-cost Operating unit are also important. The use of the aeroplane played a leading part in the development of the Northwest during the past decade. Except for the historic fur trade which was well developed, the Northwest was only beginning to open up when war in Europe was declared in 1939. As the manpower require- ments of the fighting forces and war industries became urgent, miners, trappers, traders, and others left the region, forcing many of the mines and other industries to close temporarily or to curtail operations greatly. With the cessation of hostilities the resumption of active development can now be expected principally in prospecting, mining, and tourist interest. The airfields of the Northwest will 3681—9 undoubtedly play an important réle in the future develop- ment of these industries. The present network of air routes now serves vast areas that were previously almost inac- cessible. If new resources are found, which can compete economically with those closer to present markets, it will not be a difficult matter to build a few new airfields to link these resources with the present routes. During the war years much of the preliminary work was done and plans were evolved for larger development as soon as labour and materials again became available. The written publicity that this region has received through the building of the Alaska Military Highway, the Canol Project, the Northwest Staging Route, and other war-time projects, in addition to the oral publicity of the thousands who have worked on these war activities, has created a popular urge to visit this last pioneer region. Much of the traffic will be carried by air as soon as facilities will permit. In addition to the present aircraft and landing fields and seaplane bases, facilities must now be expanded to include modern accom- modation for the public, and refuelling and repair facilities for privately-owned aeroplanes. The commercial aviation organizations now serving the Canadian Northwest will have to expand their present facilities to meet the increasing demand, and as materials become available, provide modern aircraft equipped to carry various types of freight and passenger trafic. Unlike railroads and highways, airways can be provided, expanded, or contracted, more easily as demand dictates. It is assumed that Canadian enterprise will be alert to the possibilities of development in the field of local air transport. Although northern Canada has been publicized as “the crossroads of the world” for future air routes, much of the area offers very little freight and few passengers for through trafic. The Northwest Staging Route saves time and distance for direct flights from eastern Canada and United States to eastern Asia, but many commercial flights are interested in local traffic along the way. The Pacific Coast route from Seattle to Anchorage and Nome and the Aleutians is now being used once more by Pan-American Airways, assisted by additional aids to navigation and airports built during the war. Advances in the techniques of high altitude flying, radar navigation, and Operations in cold regions, have all increased the eficiency and safety of long-distance flights, and have overcome some of the natural hazards of flying in the Pacific Northwest. Regardless of which route ultimately carries the bulk of international air traffic to Asia, the presence of the inland route through northwestern Canada will be important to the local development and administration of the region. Although the “transit” character of long-distance flights will not greatly aid the Northwest directly, the facilities at the airfields will have to be kept on a high serve this traffic, and will be available for loc flying. standard to al Canadian Since smaller Canadian companies will be more [129 }
