Do we actually have developer approved plans for the greenery? English Ivy is an invasive species ( as are other ground cover types such as periwinkel)
The Toronto Master Gardener is quoted in a number of places so: Instead of English Ivy, Periwinkle, Goutweed, or Lily-of-the-Valley, the Toronto Master Gardeners suggested that you grow: Virginia creeper (Parthenocissus quinquefolia); Wild Ginger (Asarum canadense); Canada Mayflower (Maianthemum canadense); Woodland/wild Strawberry (Fragaria spp.); or Bunchberry dogwood (Cornus canadensis).
Others may have further information?
