In a pot over medium heat, drizzle in a bit of olive oil and drop in the bacon, Render the fat and cook until bacon is golden brown and crispy. Remove and set aside.
Into the bacon fat, add in the cubed celery, carrot and onion. Saute for 3-4 minutes or until the veggies are soft and translucent. Add in the flour and Old Bay seasoning and cook out the floury taste for 2 minutes.
Pour in the white wine and reduce to cook off the alcohol. Add in the potatoes, bacon and stock, cover and bring a boil. Simmer until the potatoes are soft and the soup is slightly thick. If the soup is not thick enough, you can add a bit of cornstarch slurry until the desired thickness is achieved. (cornstarch slurry is equal part cornstarch and water mixed into a slurry).
Add in the seafood and cover. Let simmer again until the seafood is cooked through (it shouldn't take long). Finish with the cream, parsley and season to taste.
Serve with toasted bread.
