Tim Hortons brewed coffee has more caffeine than Coca-Cola Classic on both counts: 140mg per 14 oz medium against 34mg per 12 oz can, and about 10mg per fluid ounce against 3. The serving sizes differ, so the table below shows both ways of counting.
These are different categories of drink, which changes how the caffeine arrives. Energy drinks and sodas list an exact number because caffeine is a measured additive; brewed drinks vary with the beans and the brew, so their figures are compiled averages. The numbers here are the standard published values for each.

The concentration gap is the striking part: Tim Hortons brewed coffee packs roughly 4 times the caffeine per ounce. Sipping speed matters at that density; a 14 oz medium finished in minutes hits differently than the same milligrams spread over a slow cup.
Which one should you pick?
Pick Coca-Cola Classic when you want the lighter dose or a slower ramp, and Tim Hortons brewed coffee when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
