Ottawa, ON → Montreal, QC

The drive from Ottawa to Montreal is one of Eastern Canada's most straightforward highway journeys, taking you along Highway 417 eastbound from the nation's capital before transitioning to Highway 20 as you approach Quebec. This roughly 134-mile route typically takes about two hours and fifteen minutes under normal conditions, making it an ideal day trip or a pleasant connecting drive for anyone traveling between these two major metropolitan areas. The highways are well-maintained and clearly marked, with ample signage to guide you through the transition from Ontario into Quebec near the town of Hawkesbury.

As you travel eastward from Ottawa, you'll notice the landscape gradually transitions from the urban sprawl of Canada's capital into the agricultural and forested terrain of the Ottawa Valley. The terrain is relatively flat throughout this corridor, with gentle rolling hills characteristic of the Canadian Shield's southern edge. Around Hawkesbury, you'll cross the Outaouais region, where the landscape becomes noticeably greener and more densely forested. As you approach Montreal from the west on Highway 20, the land begins to flatten again as you enter the St. Lawrence River lowlands, with occasional views of the river itself as you near the city.

The drive takes you through several smaller communities including Hawkesbury and Coteau-du-Lac, which offer brief glimpses of small-town Quebec life but aren't major detours from the highway itself. Montreal's approach is marked by increasing suburban development, and you should expect heavier traffic and more complex navigation once you're within about thirty kilometers of the city center. Highway 20 merges into the metropolitan area with multiple lane options, so knowing your final destination in advance is helpful for choosing the correct exit.

This route is most pleasant during spring through early fall, when clear skies and comfortable temperatures make for easy driving. Winter conditions can be challenging, particularly on Quebec's Highway 20 near Montreal, where snow and ice may require extra caution and reduced speeds. Summer travel is ideal, though mid-morning departures help you avoid peak traffic around Montreal during rush hours.
