I think you mean the advent of car culture.
Our current system relies on the economic externality of relying on private vehicles and private transportation on local infrastructure to artificially lower the transportation costs for grocery logistics. It's much cheaper to run an 18-wheeler to a large grocery store on the edge of suburbia than running box trucks all over town. It doesn't actually lower food costs, because people pay a large fraction of their income to that private transportation so that they can access that super-grocer, and then the grocer seems to jack up the price of food anyway.
The debacle is the MPs and NDP falling for the populism carrot that is carve-outs. It won't be the last one either. It will always be framed as "helping the old lady keep the heat on" and not what is is - an oil subsidy that keeps people tied to a highly price-volatile and polluting heating source. You can also help that old lady by tweaking the rebate algorithm, but that wouldn't help out the oil industry near as well.
