Explanation:

The Indian federal system is based on the ‘Canadian model’ and not on the ‘American model’. The ‘Canadian model’ differs fundamentally from the ‘American model’ in so far as it establishes a very strong centre.The Indian federation resembles the Candian federation:
a) in its formation (i.e., by way of disintegration);
b) in its preference to the term ‘Union’ (the Canadian federation is also called a ‘Union’); and
c) in its centralising tendency (i.e., vesting more powers in the centre vis-a-vis the states).
