Emotionally distraught re: plastic grocery bags missing from my life

So I finally ran out of grocery bags to use for my trash cans at home and went to shoppers to buy some and wow are they expensive. I used to pay 5 cents a bag, now I'll have to pay 20-30 cents a bag. I live in downtown, does anyone know whom I should contact about my disgruntled feelings in the city? I don't understand why I have to buy expensive garbages bags now instead of using grocery bags, when they're all going to the same place in the end. Is it actually better for the environment? Like... Maybe if the city banned small garbage bags and told everyone to use huge bags going forward I would understand, but I for one am still producing the same amount of plastic waste but paying more for it.
