I'm an American who visited Costco in Canada and found that while it looks identical it's not the same

Growing up, my parents loved Costco because they could purchase foods for our family of four in bulk for low prices. I remember spending Saturday afternoons exploring the warehouse with my brother while my parents shopped for produce, snacks, and everything in between with their membership.

While Costco started in the US — its first location opened as a Price Club in 1976 in a converted airplane hangar in San Diego, California — the wholesale outlet is now in eight countries, including Canada.

As I learned on a recent trip there, Canada is home to more than 100 locations, according to Statista. While I was there for the first time, I stopped by a location in Niagara Falls, Ontario, to see how it would measure up to US stores.

Turns out, it's pretty similar — but there were a few things that I found to be different.

The largest Canadian retailer is Loblaws, a supermarket chain, according to Statista. Costco surpassed Sobeys, Metro, and Walmart, according to the same source.

When I walked into Costco, I was immediately transported to my home country because the inside of the warehouse looked exactly like its counterpart stores in the US.

Ramsey Monroe, a Costco fan who has been to more than 200 locations around the globe, previously told Insider that the layout is similar in every store she's been in.

"If I ever feel homesick, I can just go to Costco," Monroe said. "I just feel at home at Costco so no matter where I am in the world, it's just comforting."

According to a report from Statistics Canada, more than 20% of the country's population speaks French as their first language.

While French is the primary language in Québec, according to the report, it's the minority language in Ontario — the province where I visited Costco.

Since winters are colder in Canada, I thought this made sense.

Canada has one of the harshest winters of any country in the world because of its high altitudes and location up north, according to the Government of Canada. Dressing for the weather is essential to combat frostbite, windburn, and hypothermia.

All Costco warehouses locally source vendors, as Insider previously reported.

During my visit to the Niagara Falls store, I spotted maple leaf cookies, orange mango quinoa cookies, and Hungarian beef sausage among other items that I haven't seen at Costco in the US.

From bison burgers to Wagyu beef, Costco stores in Canada have a wide variety of locally sourced meats.

The US has a variety of locally sourced meat and seafood as well, from Chicago steaks to bone-in pork cutlets.

I see Aero chocolate bars — a popular treat in the UK and Ireland — in the US every so often, but they're not widely available in my experience. According to Mashed, they're hard to find outside of Amazon.

So I was surprised to see them being sold in bulk in this Costco. As I learned later reading Nestlé's website, it turns out the bars are widely sold in Canada, Australia, South Africa, and Japan.

Tim Horton's is a popular coffee brand and fast-food breakfast joint based in Canada.

I got a breakfast sandwich and an iced coffee drink when I visited the chain, and thought the food tasted fresher than that from most fast-food restaurants I've been to.

Although I didn't get a chance to try it for myself without a membership, I noticed that the food court carried poutine, a popular Canadian dish that has three ingredients: fries, gravy, and cheese curds.

Later in my trip, I went to La Banquise, a restaurant in Montréal known for poutine, and I really enjoyed it. The fries were crispy and greasy — just like I like them. I thought the gravy was reminiscent of Thanksgiving dinner, and the curds added a unique texture without adding too much flavor.

Although I was outside of the US, visiting Costco in Canada felt like a taste of home. With a nearly identical layout to the American stores I've been to, I felt transported to my childhood as I strolled the aisles.

If I ever find myself in a Canadian Costco again, I'll pick up some Aero, Tim Horton's coffee, and poutine.
