geologist and enginner have the same professional status in Canada. Both are regulated under professional act and enjoy the same pay. there is geolgoical engineering in Canada university. You can goole out such universities in canada and US. Geotechincal enginnering is defined as "soil mechanics and foundation" in westen. It is only part of geological engineering and part of civil engineering.
In westen, especially Canada and US, engineering and science are totally different in university though they penetrate into each other in specific projects. they have different focus in purpase, methodology, and result.
try to see things in big picture. most geologists works in resources sectors, like resource development, management, and environment; and in government. currently more consulting companies have to hire geologists to handle the environmental projects.
all materials can be divided into two catertories: geological material-materials created by geolgoical process; and man-make material-materials created by human-being by transforming geological materials. geological materials accounts for major part of all materials. from this you can understand how important it is to understand the earth.
so to understand things in aborad, we have to open our eyes and see big picture.
