In Canada any party on a phone call can record without the consent or awareness of other parties. In the case of calling customer service, the agent you end up speaking to is very likely not the one actually doing the recording, but they are aware of it, thus they fulfill the requirements of single party consent. You are correct that placing a camera and not being present while it records does not make you a party, but if you make it clear (verbally, signage, blinking light from a camera on your windshield) that a camera is recording in your vehicle and they choose to work on it they are a consenting party. The law says that you cannot record where people have a reasonable expectation of privacy, but that is meant to apply to places like bathrooms, change rooms, saunas and other similar places.
