Of course, lateral entry syllabus is same as B.Tech for every branch.

Canada is best for civil engineering as construction work goes on in Canada, so in terms of job prospects also it is beneficial.

It is difficult to get into Sastra University, unless you score 900 and above. But, if luck goes your way, then you will get it.

Yes you can change your branch after first year. But every college has different criteria for changing branches. Some require CGPA above 7 you must confirm with your college rules.
