Tensions between Canada and India have escalated over the assassination of a Sikh independence advocate in June.

Canadian Prime Minister Justin Trudeau said his country was investigating credible allegations that Indian government agents were connected to the assassination of Hardeep Singh Nijjar, but India has rejected the allegations as absurd.

India has long demanded that Canada take action against the Sikh independence movement, which is banned in India but has support among the sizable Sikh diaspora populations overseas, including in Canada and the U.K.

Here is a look at the relationship between the countries, by the numbers:

POPULATION Canada is home to nearly 1.4 million people of Indian ethnic or cultural origin, about 3.7% of the country's total population, according to the 2021 census.

More than 770,000 people reported their religion as Sikhism, about 2% of Canada's population, and in 2019, the government designated April as Sikh Heritage Month.
