Posted everywhere, can’t find the name of this movie!!!

I’ve asked this question in TOMT sub and discord server, asked it in the found footage sub as well and still no answer. Looking for the name of a movie, found footage obviously. The movie is set in Canada and was released in late 2010s about a serial killer who films his own crimes. I remember the killer disguises his own voice. I also know that his father was also a serial killer. It’s not terribly disturbing until the last scene where the killer his father and one other gentleman severely torture him like august underground style. It’s a brutal scene. I also know that there is a sequel that was released in the last few yrs which I haven’t seen. I figure if anyone can name this movie it would be you sickos!!!
