Check provincial window tint laws before installation—fines for illegal tint are common

For dash cams, hardwired installation is cleaner and provides parking mode functionality
Verify that truck accessories are specifically designed for your year, make, and model
Ask about warranty coverage on both the parts and the installation labor

Frequently Asked Questions

How much does remote start installation cost in St. Thomas? +
Professional remote start installation typically costs $300-$600 including the unit, depending on vehicle complexity. Push-button start vehicles and newer cars with encrypted key systems are at the higher end.
Will aftermarket accessories void my factory warranty? +
Under the Competition Act, a manufacturer cannot void your warranty simply because you installed an aftermarket part, unless they can prove that specific part directly caused the failure being claimed.
How dark can I legally tint my windows? +
Window tint laws vary by province. Most provinces allow 35% Visible Light Transmission (VLT) on front side windows and any darkness on rear windows. Your installer should know the local regulations.
Is a dash cam worth installing? +
Yes, dash cams provide critical evidence in accidents and insurance disputes. A quality hardwired dash cam with parking mode also protects your vehicle when parked by recording hit-and-runs and vandalism.
