Google has like 3/4 of the phone market. I didn't know they tracked my location by default for a long time, and though I thought I turned it off I still get random notifications from google maps asking me to rate a restaurant I just ate at.

EDIT: grammar

The cell service provider can also track you, and you have zero control over that. They may be sharing your location info with many parties, including google.

I don't think there's a technological fix for avoiding location tracking of connected devices. The network must know where you are in order to deliver the connection, and you cannot control the network. Any control given at the device level is therefore an illusion. The only comprehensive solution is a legislative one. Outlaw improper use of location tracking information (GDPR-style), and allow people to use the courts to force good behavior.

I live in Canada. Canadian companies have to abide by certain privacy laws. Google is a foreign company and what rights do I have as a non-us citizen?

In T-Mobile Account Settings you can choose to disable T-Mobile's selling of your data to third parties. It's on by default.
