A diner breakfast is a classic meal that has provided a hearty start to the day for generations of Canadians. The meal itself seems simple enough, but a lot goes into making it.

When diners started serving up breakfast well over a century ago, many of the ingredients would have come from local farms. Today, the ingredients on your plate can come from halfway around the world—even if there’s a farm just a few kilometers up the road.

Canada is a major exporter of pork products like bacon and sausage, but we also import pork products. So even if there’s a farm nearby, it’s possible that the bacon on your plate came from the United States or Europe.

Canada is one of the world’s biggest producers of wheat, so there’s a good chance that the wheat used in your toast and pancakes was grown in Canada. But wheat can still travel a long way. Most Canadian wheat is grown on the Prairies, while most commercial bakeries are in Ontario. That means wheat grown in Saskatchewan might be processed in Toronto and then shipped back as bread.

Orange juice goes down easy with any diner breakfast, but it can travel even farther than some other ingredients. Much of the orange juice sold in Canada comes from Florida or Brazil.

Coffee beans are also grown in the tropics and must travel thousands of kilometers to reach Canadian diners. All of these different farming operations require inputs to cultivate the crops that feed people in Canada and around the world. Fertilizers and pesticides improve crop yields, and diesel fuel powers large-scale harvesters.

So when prices for energy and fertilizer go up, that drives up costs for farmers—and, in turn, the prices of all these food items. The price for any one of these ingredients can also rise if a farming region is struck by drought or a natural disaster.

All of these factors can affect the price of the food served up at your local diner.
