Thanks to Shane, I finally ended up doing the below loop which was long overdue. The below was the route suggested by Shane:

It was the best ride I have had so far this season. A lot of nice roads once you reach country rd 48 east to Rohallion and further. The only change I made in the above route was to hit Five Corners on my way back. So the route really looked something like this when I completed the trip:

Washroom situations - First stop was at Shell on Hwy 48 and 23; no washrooms.
The second stop was at Queen of Fries to grab a quick bite. There is a portable toilet there. Can't comment really on the food as I just ate poutine - no other veg options that I could see. It was either fries or poutine and I went with poutine lol. In my book, poutine is good even if it's bad...
The third stop was at Gooderham at the gas station near the 503 and 507 intersections. Washrooms were available and pretty decent.
The fourth stop was on my way back home - 401 E and Road 26. Shell gas station had a decent washroom as well.
I took a few more stretching breaks too other than these above stops. A few good souls stopped to ask if I was okay when stopped on the roadside, and a motorcyclist on 115s. I may have moved my hands and legs weirdly but that was because everything was numb from the vibrations and my a** was grass sitting on that park bench for that long lol. But seriously thank you!
Update: 507 is under construction and I had read it on the forum. But still went ahead and took that route. Approx. 5 km in the middle is loose gravel, under construction and there is another spot that is being dug up by heavy machinery. Traffic is slow in those parts but I didn't really have any concerns. The rest of the road made up for whatever inconveniences I faced and it was pretty nice.
I did meet a few bikers along the way. Somewhere on Monck Rd, a cruiser on the speed limit. I had to overtake as I was doing 20 above the limit and the road was empty. If you're on the forum, cheers. 2 bikers who were behind me on 507 but disappeared before I took a left on 36.
Out of all the roads, Northeys Bay road was my favorite if I think of it.
