What is the fine for driving with a blocked window view in Ontario?
In Ontario, section 74 of the Highway Traffic Act requires that the windshield and side windows provide a clear view to the front and side, and that the rear window provides a clear view to the rear unless mirrors are securely attached and maintained to otherwise provide a clearly-reflected view. If you are convicted for driving with an obstructed window view, the offence is generally punishable by a fine of up to $1,000 plus the victim surcharge and court costs, since section 74 does not set a specific penalty.

Understanding the Requirement That Drivers Have Views Through Windshield, Front Side Windows, and Rear Window
For plain and obvious reasons, a driver must have an unobstructed view through to both front-seat windows and through to the rear window of a motor vehicle. If viewability through the rear window is obstructed, such is permitted so long as the driver is able to use side mirrors as an alternative to a view through the rear view mirror.
The Law
The Highway Traffic Act, R.S.O. 1990, c. H.8, prescribes the legal requirements regarding the requirements for a driver to view through windows whereas it is stated:
Windows to afford clear view
74 (1) No person shall drive a motor vehicle upon a highway,
(a) unless the windshield and the windows on either side of the compartment containing the steering wheel are in such a condition as to afford the driver a clear view to the front and side of the motor vehicle; and
(b) unless the rear window is in such a condition as to afford the driver a clear view to the rear of the motor vehicle.
Application of cl. (1) (b)
(2) Clause (1) (b) does not apply to a motor vehicle that is equipped with a mirror or mirrors securely attached to the motor vehicle and placed in such a position and maintained in such a condition as to afford the driver, otherwise than through the rear window, a clearly-reflected view of the roadway in the rear or of any vehicle approaching from the rear.
As per the law provided above, the driver must be able to experience a clear view through the front windshield, the front seat compartment side windows, and the rear window with an exception for review through the rear window when side mirrors are an available substitute for rear direction viewing.
Potential Penalties
Interestingly, section 74 of the Highway Traffic Act is silent regarding the potential penalties for driving without proper window viewability; and accordingly, the general penalty of a fine of up to one thousand ($1,000) dollars applies for offences without a specified penalty apply. In addition to a fine, adverse affects to insurance rates may also result upon a conviction.
Summary Comment
Drivers must be able to experience an unobstructed view through the front windshield, front side windows, and rear window. Side mirrors as a substitute to visibility through a rear view window are a permitted exception. A potential fine of up to $1,000 applies for having obstructed window views.
