CHANDIGARH, India: Indians in Punjab, worried that plans to work, study or visit families in Canada will be jeopardized by this week’s tit-for-tat expulsions of diplomats over the murder of a Sikh separatist, are urging both governments to reduce the tension. Canada’s nearly 800,000 Sikhs formed the world’s second largest community in 2021, after roughly 20 million in India. They have links to the northern granary state of Punjab, where their religion was founded more than 500 years ago.
