Your weekly pizza night might get a little more expensive, as Pizza Pizza has quietly introduced extra charges on select pizza toppings.

It's unclear when the extra charges started, or why, but if you love topping your pizza with any steak or chicken products, you'll now have to pay for it.

Pizza Pizza doesn't list how much the extra charge is on their menu, so we created 2 small pizzas -- one with extra charge toppings, and one without -- so that we could determine the cost. After creating our 2 pizzas, we were able to see that the chain is now charging $1.00 each for these "premium" toppings.

Toppings on the menu that now have an extra $1.00 charge include:

• Grilled Chicken
• Sriracha Chicken
• Buffalo Chicken
• Chipotle Chicken
• Pesto Chicken
• Steak Strips
• Chipotle Steak
• BBQ Steak Strips

Are you surprised to hear about the new extra charges at Pizza Pizza? Will this change how you order? Let us know your thoughts in the comments!
