Several paragraphs from that website:
**** Aerating ****
The reason for aerating is to amend compacted soil that no longer has adequate pore spaces for air and movement of water. This is most often accomplished with a machine that removes plugs of soil.
In order for this process to be successful the grass must be topdressed after aeration to fill the holes in the soil with organic matter (or screened topdressing soil).
Otherwise the existing compacted soil gradually fills in the holes left by the machine leaving the lawn uneven, and the walls of the cores susceptible to drying out, damaging the roots adjacent to the core holes.
Fall is the best time to aerate and topdress compacted soil in Ottawa because the soil is drained, warm and the temperatures are pleasant during the day and cool at night. It is a temperate long-lasting season unlike spring, which is abrupt and often has great temperature fluctuations in Ottawa
**** Water your grass wisely ****
Water thoroughly
A weekly soaking helps to strengthen grass roots and promote a healthy lawn. Frequent light watering results in shallow roots and unhealthy grass.
Don't overwater
Your lawn needs 2 cm to 3 cm (0.8" to 1.2") of rain or water a week, more during periods of drought. After a rainfall of 2.3 cm (1"), skip a week. Overwatering wastes water. Place containers in various spots in the sprinkling area to judge the amount of water being used.
Water when it's coolest
Water your lawn in the morning or late afternoon, but don’t water it in the evening when prolonged dampness can cause disease and fungus.
