I found a company that deals with alarm systems. https://cspalarms.ca/monitoring/ They're based in Toronto and has extended their services to other regions. I'm a bit skeptical about ordering from them despite having talked to their security specialist. He also explained clearly why most burglar attempts are discovered only after they have looted households - because the alarm systems aren't loud enough. He stressed on the need to have annoying alarms (they only go off once a while unless you live in an area with really high crime rates). They even have a 16 channel DVR system. I wouldn't be needing many cameras and I'd probably opt for the standard one.
I'm not willing to conduct a trial and error experiment. So before I proceed any further, could someone rate them on a scale of 1 to 10? (I'll order if 8 and above).
PS: Would be better if you have experience using their services.
