If the windows face your sideyard there are building code maximums of allowed unprotected openings. Calculation of the percentage is based on the setback distance and the area of the exterior of the house facing the sideyard.
Typical 1.2m setback in most cases allows 7%. Wall area is calculated from grade to ceiling level. Check with an A.T. or the City.
