Toronto/Jalandhar, March 6 -- An outspoken critic of pro-Khalistan separatists and a prominent Punjabi social media influencer has been murdered in the town of LaSalle, Ontario. The victim, identified by local law enforcement on Wednesday as 45-year-old Nancy Grewal, succumbed to injuries after being stabbed at a residence on Monday night. Grewal, originally from Narangwal village in Ludhiana, moved to Canada in 2018. While the LaSalle Police Service has described the homicide as an "isolated incident" to ease public concern, Grewal's family in Jalandhar has alleged a targeted campaign of intimidation by hardliners. According to the LaSalle Police, emergency units responded to reports of a stabbing on Todd Lane, between Canada and Bishop streets, shortly before 9.30pm on Monday. Grewal was found with critical injuries and transported by Essex-Windsor Emergency Medical Services to a local hospital, where she later passed away. Detectives are currently seeking video surveillance from residents in the vicinity. "The investigation into the homicide is ongoing," the police department said, though they have not yet confirmed if any suspects are in custody or disclosed a specific motive. Speaking in Jalandhar, Grewal's mother, Shinderpal Kaur, 70, said her daughter had been receiving frequent death threats from hardliners over her digital content. "Local radicals objected to her content and developed an enmity with Nancy," she said, adding: "Two months ago, unidentified miscreants set her house ablaze. She survived and reported it to the police. She even received a death threat letter recently; we have provided the names of three suspects to the authorities." Kaur alleged that the Windsor-based Gurdwara, which Grewal frequently visited, had become a "hub of radicals" who took issue with her questioning the management and her vocal opposition to separatist ideologies. Kaur further alleged that a man with a covered face had once attempted to enter her daughter's house. "The intruder, however, fled noticing CCTV cameras installed inside and outside the house. My daughter managed to recognise him," she added. After moving to Canada in 2018, Grewal built a significant following, nearly 9,000 subscribers on YouTube and 12,000 on Instagram, by posting sharp, often controversial commentary on Punjab politics and Sikh issues. She frequently challenged proponents of Khalistan, often using the derisive term 'Khotaistanis' (fake nationalists). Her recent videos included critiques of various Sikh religious issues. Her mother said that Grewal's videos were often under the scanner for their "sharp criticism and strong epithets". "I usually asked her to change the verbal context or not to upload if the language was too offensive," Kaur said. The family learned of the tragedy on March 4 after Grewal failed to answer multiple calls, prompting them to contact her employer and local police. Grewal had been working as a caregiver in Windsor following her divorce. Shinderpal Kaur is expected to fly to Canada on March 6 to perform her daughter's last rites. Grewal's father Manmohan Jit Singh died in 2008. Her mother said: "Several reports were carrying completely wrong details of her identity....
