I've made a little video of my question since I think its best drawn out to understand my question fully.
I will try to explain it quickly via words but best to review my video.
There was a parcel of land in Ontario. An entire 200 concession lot. Lets call it Parcel A. At some point Parcel A was divided in half. Creating a new Parcel B being the south half of Parcel A leaving the balance of Parcel A as north half.
During the severance of Parcel A it became subject to a right of way for the owners of Parcel B in, over along and upon a strip of land of a uniform perpendicular width of 25 feet being the easterly 25 feet of the north half Parcel A. The purpose was that the north half has a public road running through it which connects to the 25 foot right of way. Giving the owners of Parcel B a way to cross Parcel A and get to the public road.
Later on Parcel B was then split in half. Making a new Parcel C as the north half of B. Leaving the balance (the south half Parcel B) I know that in 1.0.3 Division of Dominant Lands it says "Upon the severance of a parcel of land, all existing easements appurtenant to the whole, benefit each severed portion." But how does Parcel B cross Parcel C when C is in the middle to get to the Right of way on Parcel A. Is it implied through law that B must have to cross C to get to A or has B now been landlocked? If its implied what law or wording in the law would support this? What path would the owner of B be allowed to take across C to get to the right of way on A?
