Add canola oil to a large nonstick saucepan, and heat over medium-high heat. Add leeks, celery and garlic, and saute, stirring occassionally, until vegetables are lightly cooked, about 5 minutes. Reduce heat to medium low.
Quickly add flour and 2/3 cup of half-and-half or milk to a 2-cup measure and stir to blend well. Whisk in the remaining milk. Pour immediately into the saucepan with leeks and whisk in the broth and beer. Cook, whisking occassionally, for about 5 minutes.
Stir in the Worcestershire sauce, mustard, salt (if desired) and pepper. Add in the cheese and diced potatoes, stirring constantly until cheese is nicely melted (about 2 minutes), while making sure the soup doesn't boil.
Ladle into 8 serving bowls or cups. Add more freshly ground pepper on top and, if desired, some turkey bacon bits and/or chopped green onions before serving.
