In 1951, the Canada Life Assurance Company added an almost 100 metre tall beacon tower to the top of its stately building on University Avenue. The purpose of the tower was not to signal airplanes, but to transmit the weather forecast. Anyone in the know could look to the tower and decode the light signals to determine what was on its way, and in this, little has changed. The lights might be energy efficient LEDs now, but calls are still placed to the Environment Canada Weather Centre at Pearson several times a day to keep the beacon's message up to date, and the signals themselves are the same. The box at the top of the tower tells what type of weather is coming: steady green for clear skies, steady red for clouds, flashing red for rain and flashing white for snow. The temperature can be discerned from the lights on the support tower. If they are running up, expect it to get warmer, down means cooler, and steady means no change.
