When winds are out of the north and east like they are this morning, you'd get a brief glimpse of Toronto out of the right (DEF) side of the plane. The winds are forecast to shift out of the southwest later in the afternoon, so if your flight's landing after 4pm, your best bet is probably the ABC side, which offers a great view as the typical approach from the south flies along the lakefront before turning north and west toward YYZ.
