Canada in summer is built for road-tripping — long daylight, lakes that look filtered, and national parks without the winter crowds. June through September is the sweet spot: trails are open, ferry schedules are full, and the northern lights are traded for midnight sun if you go far enough north.
If you're working with a tighter budget, the trick is picking one region and committing to it instead of racing across the country. Most of that $380 goes to a short flight, a couple of nights, and food — which is where a bit of timing on your credit card can take the sting out of paying it all at once.
Heads up: the 18-month 0% period is a deadline, not free money. If any of that $380 is still on the balance when the intro window closes, the remaining amount starts accruing interest at the card's standard rate. Pay it off before month 18 and the math works out exactly like the spreadsheet says.
