GRE is not required and if you are talking about exchange scheme you have to get in touch with the two universities you are concerned with right now, the one in India where you are currently studying and the one in German y where you wish to go. Best is to get in touch with DAAD too. Check DAAD Delhi website for exchange programmes and norms.

Hello Rijun,
It's nice know your dreams of doing MS in Canada. The whole process normally takes about one year. I would advise you to contact a local agency dealing with sending students abroad since there are many nuances to this issue & it's perhaps outside the scope.
Your good academic career will definitely get you admission.
