Booked an Aeroplan Rewards flight earlier this year. I’ll be travelling later this year from SIN > DEL > YYZ. My layover in DEL is 13 hours, but I do NOT plan to leave the airport (especially since this current situation). I only have my Canadian Passport. Will I need to apply for an e-Visa during my transit in DEL. I.e., It’s not like China where I’d have to actually go through immigration even when transiting, is it?

Sorry for the noob question. I’ve never passed through DEL before.
