Canada tries to hide it in official statistics, but it still peeks through. Despite being a model minority in every other nation, ethnic-Indians have the 2nd highest crime rate by race in Canada[2]. Gang violence is primarily intra-race, and the over-representation of ethnic-Indian in homicide victims points its prevalence [3].
Canada's Indo-Canadian crime are limited to ethnic-neighborhoods and townships. Irishmen & italians on the west-coast would have been blissfully unaware of their respective mafias on the east coast. Similarly, unless you live in these neighborhoods, you won't notice it one bit.

Even if we go with your premise (which in itself makes a whole bunch of assumptions), South Asian homicide victim rate per 100,000 people is comparable to the total rate (and for some years significantly lower):
2019: 1.77 vs 1.84 total
2020: 1.21 vs 2.01 total
2021: 1.69 vs 2.09 total
2022: 2.35 vs 2.27 total
2023: 1.38 vs 1.94 total
So even if your argument was valid (in inference, which I'm absolutely not convinced about), the data doesn't even back it, so it is at the very least unsound.
Did you confuse Indians with Southeast Asian by any chance? That group has a little higher rate of homicide victimhood, though only marginal. SE Asian people include Vietnamese, Cambodian, Thai, Indonesian, Malay, Philippine etc nationals, not Indian/Pakistani/Sri Lankan.
I'm an Indian who has lived in Canada for a decade now, and I haven't seen or heard much about Indian immigration specifically for joining gangs or anything like that.
If anything there's more evidence that Canada's immigration crisis is a result of ridiculous barriers for high skilled workers if they don't have a degree from a North American university. Countless tales of medical professionals having to redo certifications because Canada doesn't accept their pre-existing education.
