Dear Client, 

As you are a Canadian Citizen, you can take her there to marry her validity but if you think about India, she can not get Indian citizenship as even you are not an Indian citizen. 

Thank you

To get married in India as per Indian laws,  one of the parties to the marriage should be an Indian. 

Since you both are foreign citizens your marriage may not be registered in India. 

Hence you may have to look for marrying her in that country itself. 

After that she can visit India on tourist Visa accompanying you. 

Please be guided by my earlier response.
