Travelling on Canadian passport has no relation to surrender of Indian Passport. You can surrender Indian Passport upto three years after you become Canadian without any penalty, provided you do not use your Indian Passport for travelling.a question for you? Can I travel on Canadian passport if the surrender process for Indian passport takes time? what's the fine?
Due to Covid, my wife surrendered her Indian Passport after two and half years. It wasn't used for travel during this period.
