"The India-Canada relationship is blooming and thriving," Mr Patel said at a media interaction organised by the Indian Association of Foreign Affairs Correspondents (IAFAC) here.
"We have already held four strategic dialogues," he said.
Stating that Prime Minister Narendra Modi and PM Trudeau have met both formally and informally, he said that "our leaders have developed a very strong relationship".
PM Modi had visited Canada in April 2015 when Stephen Harper was the Prime Minister. It was the first standalone prime ministerial visit from India to Canada in 42 years.
According to Mr Patel, PM Trudeau is scheduled to visit India either "late this year or early next year" at the invitation of PM Modi.
"We are yet to finalise the dates," he said.
Seven Canadian cabinet ministers have visited India in the last eight months.
The High Commissioner said that both PM Trudeau and Canadian Foreign Minister Chrystia Freeland "have made it clear that India is top priority for Canada".
"Delhi is our largest diplomatic mission in the world," he said.
Stating that bilateral trade and investment was "largely balanced", he said that there was "$14-15 billion of Canadian investment in India in the last two years".
"There are around 1,000 Canadian companies in India of which 400 are physically present," Patel said.
"There is potential do a lot more," he said.
In terms of what Canada can offer to India, he cited food security, aviation, start-ups and clean energy among various sectors.
He said that Canada was keen to have a Comprehensive Economic Partnership Agreement (CEPA) with India.
"SMEs (small and medium enterprises) of both countries stand to gain the most," the High Commissioner said.
As for the civil nuclear agreement signed during PM Modi's visit, he said that administrative guidelines have been concluded and "things are moving fast".
In this connection, he said a delegation of Canadian companies would be visiting India to discuss nuclear technology.
"Large-scale uranium supply is already happening," he stated.
With around 1.2 million Indian-origin people in Canada, Mr Patel, who's also an Indian-origin, said there are "very significant people-to-people links" with India.
Of this number, 5,00,000 hail from Punjab and there are 19 Indian-origin lawmakers, of whom 4 are cabinet ministers.
He also said that there has been a hike in the number of Indian student visas for Canada in the last four months. Asked if this was due to the policies of the Donald Trump administration in the US, he said that the surge started even before the US election and was "not attributable to the new US administration".
