But Mr Modi has not yet met the Canadian prime minister, despite him being in India for two days.
He was also absent when Mr Trudeau visited his home state of Gujarat on Monday.
And it's not just the prime minister.
When Mr Trudeau visited the Taj Mahal on Sunday, some media reports pointed to the fact that the chief minister of Uttar Pradesh, where the monument is located, did not go to greet the visiting premier.
The pictures, headlines and social media frenzy that usually accompany Mr Trudeau's overseas travels have also been largely missing.
So is India really cold shouldering Justin Trudeau? And if so, why?
"Yes, this is a major snub. The fact that a junior minister was sent to receive Mr Trudeau and his family is most definitely a snub," columnist and economist Vivek Dehejia told the BBC.
Mr Dehejia said the reason for Mr Trudeau's lukewarm reception could well be that several members of his government were closely allied with a Sikh independence movement - the Khalistan movement - which seeks to create a separate independent Sikh homeland in the Sikh-dominated northern state of Punjab.
Former diplomat Kanwal Sibal told the BBC that it would be both politically and professionally "wrong" for India to begin a state visit by Mr Trudeau with the "prejudice" of Khalistan when it could be used instead as a platform to raise India's concerns with Khalistan at the highest level.
"It is true that domestic political reasons have meant that India has not got the kind of support on the issue, but we can use the visit to get a commitment of action from the Canadian government," he said.
Mr Sibal also said he believed it was "not true" that India was snubbing Mr Trudeau, saying that relations between the two countries improved "dramatically" in the recent past, with the signing of a nuclear deal showing that they had "common interests" now.
