Linden ave.. but that area is a bit of a hot spot these days
Eoth- eagle on the hill. that can be like 50 or so with windbraking, but you are fairly safe as the median strip divides you from oncoming traffic.
Aldgate Valley- its like 40-50 with corners (need a car i might add)
Birch- can do runs by walking up laurel which is at the bottom.
Driveway- its a surburban run with corners and stuff, but can practice your sliding and stuff there as well. (ellerslie drive)
