What to do with the daylight
Aurora watching is a night job, and in winter that leaves a short, bright day to fill. Glenfield-Jane Heights keeps its fortified past above ground, at Casa Loma and CN Tower, and for a day when the cloud sits low, Bata Shoe Museum, The Royal Ontario Museum and Gardiner Museum are indoors and near by.
Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.
