Westborough, MA → Ottawa, ON

This nearly 300-mile journey from Westborough, Massachusetts to Ottawa, Ontario is a straightforward northbound trek that blends New England charm with the transition into the Canadian Shield landscape. You'll begin by heading north on I-190 from Westborough, quickly merging onto I-290 and then I-391, which carries you through the hill country of central Massachusetts. The route then connects to I-91, one of the Northeast's most reliable north-south corridors, which you'll follow through Vermont and into the Connecticut River Valley. As you progress northward, the terrain gradually shifts from the rolling hills of southern New England into the more dramatic elevation changes of the Green Mountains, offering increasingly scenic vistas as you climb toward Vermont's interior.

Once you cross into Vermont on I-91, you're entering genuine hill country where elevation gains become more noticeable and the landscape opens up considerably. You'll pass through or near several charming New England towns, including the college town of Northampton, Massachusetts and eventually the upper Connecticut River Valley region. The drive through Vermont showcases classic Northeast scenery, particularly as you approach the Canadian border—dense forests, mountain views, and clean air replace the suburban corridors of Massachusetts. In the final stretch, you'll transition from I-91 near the Vermont-Quebec border, following Highway 55 across the Canadian border and continuing on Quebec and Ontario highways until you reach Ottawa's urban area.

This route involves minimal truly congested driving once you escape the Boston metropolitan area, though I-91 through central Massachusetts and northern Connecticut can experience moderate traffic during weekday commutes. The elevation changes are moderate but consistent, with the most significant climbs occurring through central and northern Vermont—nothing extreme, but sufficient to notice the engine working a bit harder. Spring through early fall represents the ideal driving window for this route, offering clear conditions and spectacular foliage, particularly in September and October when Vermont's famous autumn colors are at their peak. Winter driving along this corridor demands caution, as northern Vermont and the approach to the Canadian border frequently experience snow and icy conditions that can significantly extend your travel time.
