Yes, most Indian visit visas that Canadian citizens get are for multiple entries, particularly the one and five-year e-Tourist visas and normal tourist visas. So, people can enter and exit India as many times as they want while the visa is good. But each visit has to follow the rules about how long people can stay: for example, with an e-Tourist visa, people can only stay for 90 days each time. People should always read the rules on their visa or ETA for the exact entry restrictions.
