I worked an hour and a bit north of Toronto in a town called Minesing.
On that house I was helping the carpenter that exposed me to timber framing. It is his house. He likes to keep changing the top plate corner post connection. I'm sure he lies awake at night dreaming up the connections. His last frame, a garage sized shop featured the cog joint where the top plate meets. I'm not sure about the house but in garages it has always been an issue keeping tie beam and the top plate high enough for a door but low enough to not make the building height higher than the city allows.
I've often wondered how you attach the edge of the decking when the girt is a different height than the tie beam?
