Organized car theft attempt — caught people twice trying to steal my Audi SUV, advice on protecting it?

A few nights ago around 8 p.m., we caught some guys trying to get into my Audi SUV that was parked in my courtyard. We ran out and scared them off, then called the police. The officers said that based on the type of car, the direction the getaway vehicle was parked, and other details, this was very likely organized theft activity — possibly people who had spotted my car earlier and either followed us or planted a tracker.

That same night, we moved the car to a friend’s courtyard that’s closed off by a metal gate, with another vehicle parked in front blocking any direct line of sight from the street. Despite that, around 5 a.m. my friend called to say a man had jumped the gate and was seen wandering right around my car, with another vehicle idling out front — presumably a getaway car.

At this point, it seems almost certain they used a tracker because there’s absolutely no way they could have found the car again otherwise. The police also mentioned that since the car is registered outside Quebec, that can make it easier for organized groups to target it.

Has anyone here dealt with something similar or have suggestions for how to protect the car while still being able to use it day to day? I haven’t slept properly in days.

Any reliable anti‑theft devices or secure places to park long‑term (multiple days or weeks) — anything that could realistically deter them or help me sleep?

Edit: I already have a steering wheel lock, tracking devices, and put it in a secure location but I am still worried. I only have a few days/weeks left here, I am moving away from Montréal soon but I would really like to be able to park it closer to mine so I can check on it more often but I just don’t know if it’s worth it to put it in my courtyard or street again so I can take a look when I wake up in the middle of the night or if I should leave it in a secure parking.
