About the Chicago → Toronto route
Chicago to Toronto is one of those routes that punches above its weight. At 702 km and roughly 50 minutes in the air, you're barely at cruising altitude before the crew is collecting cups. Air Canada, American, and United all run this corridor, which tells you everything — it's a serious business route with enough leisure traffic to keep fares competitive. I'd call it a short-haul workhorse. Suits on Monday mornings, families on Friday afternoons. The proximity means you'll see a lot of connecting passengers too, since both ORD and YYZ are major hubs with enormous onward networks.
Why travel from Chicago to Toronto?
Toronto earns the trip on its own merits. If you haven't walked Kensington Market on a Saturday, you're missing one of the most genuinely interesting neighborhoods in North America — independent food stalls, vintage shops, zero corporate polish. Beyond that, the city pulls American travelers for a few very specific reasons: NHL games at Scotiabank Arena, world-class dim sum that rivals anything in San Francisco's Chinatown, and a craft cocktail scene that's quietly excellent. Business travelers make this run constantly for financial sector meetings downtown. And with a huge Canadian-American family connection population, a big chunk of seats on any given AC flight are people visiting relatives. There's always a reason.

Practical tips for ORD → YYZ
Late spring and early fall are the sweet spots — fares soften after March Break madness and again after Labour Day, and Toronto's weather is genuinely pleasant. Budget for Canadian dollars; the exchange rate usually favors Americans, so cash goes further than you'd expect. Customs at YYZ can be slow, especially clearing the CBAF preclearance — build in buffer time. From the airport, the UP Express train runs directly to Union Station downtown in 25 minutes for around CAD $12, and it beats any taxi hands down. No visa required for US citizens, just a valid passport. One gotcha: there's no jet lag, but the time zones are identical, so don't use that as an excuse to miss an early meeting.
