So what's driving Canada's coffee binge? Our long, cold winters are certainly a factor.
"There's definitely a correlation between ambient weather and hot drinks consumption," says Euromonitor research analyst Mark Strobel.
Although Stewart is enjoying a hot cup of Joe on a hot summer day, he agrees cold weather helps fuel his craving.
"With the colder temperatures, long winters, what have you, waking up in the morning to a nice warm cup of coffee, oh my god, it's tranquility."
In Euromonitor's coffee rankings, the U.S. took ninth place. Strobel, who is based in Chicago, notes that while some U.S. States endure cold winters, hot drinks aren't that popular in the warmer, southern regions.
Instead, many people in America's south opt for soft drinks, says Robert Carter of Toronto-based market research company NPD Group.
"You can tell an American in Canada when they have Diet Coke for breakfast."
