Some more information for those who are curious...
A map created in 1877 which shows the house and gives the name A. N. as the occupant:

Alexander Nelson was born somewhere in Upper Canada in 1940, if he was indeed born in Ontario County then it was only three years after the Mackenzie Rebellion. There would still be a lingering hate towards the elitist monarchists giving choice lands to their peers and to the Anglican church (but not other denominations).
It is a question of why someone with such a small property be a farmer? My only suggestion to this is that he worked the fields of Andrew Lapp (A then, 48 year old, German Presbyterian) his neighbor, from which he received his property to build from.
As mentioned earlier, there was a masonry mark of J. PRICE (John Kerr Price was a bricklayer at the Don Valley Brickworks). Price was aged 40-50 when the house was made. It is unknown whether he made the 40KM journey to lay the bricks or only baked them.
Another curiosity I found was that a search of the 1881 census does not show a 41-42 year old Alexander Nelson, suggesting an early death or an emigration some time between the years 1877 (the time the map was made) and 1881 (the time the census was issued).
It also stated that he was married, but to whom? One theory that I had was that he moved on to his spouse's land, as there was no one with the same last name as him in the area. However, that was quickly debunked with a search of his neighbours. The answer to this question will come with a visit to the local cemetery, as it is customary to bury spouses together (barring divorce, of course.)
Additionally Amberlea Presbyterian Church was not formed until 1875, and it is in southern Pickering, there has to be another church that predated it in the northern portion of Pickering.
I thought I saw an abandoned church on **PM ME FOR LOCATION** (it is near Altona) across the street is a cemetery which may unlock more about who occupied this house that was burnt down.
