Does anybody know the criteria used for deciding which of the parks were included in the current TTC System Map? The major ones make sense, but the less prominent seem arbitrary. Some parks are more popular and are at the very least the same size, yet do not appear on the map.

The tunnel I know of only takes you halfway to NYCC (GoodLife) from across the bottom northwest exit of Sheppard Centre. Easy to miss, I was unaware of its existence for a long time until someone showed it to me.
