Mississauga, ON → Markham, ON

The direct route from Mississauga to Markham spans roughly 31 miles and typically takes about half an hour, making it one of the more straightforward drives across the Greater Toronto Area. You'll primarily use the Queen Elizabeth Way heading east, which transitions into the Gardiner Expressway as you approach Toronto's waterfront, before connecting to the Don Valley Parkway northbound toward Markham. This heavily trafficked corridor is the backbone of GTA commuter traffic, so you'll want to time your departure to avoid the notorious rush hour congestion that typically grips these highways during weekday mornings and evenings. The route hugs the northern shore of Lake Ontario for a portion of the journey, giving you occasional glimpses of the water, particularly if you take the scenic lakefront sections near Port Credit before merging onto the expressway system.

As you progress through this urban-to-suburban corridor, the landscape shifts noticeably from Mississauga's mixed commercial and residential zones into Toronto's denser downtown core, then gradually opens up as you head north toward Markham's more suburban character. The Don Valley Parkway cuts through a significant ravine system, offering some pleasant relief from the urban sprawl with tree-lined banks and green space that punctuate this otherwise concrete-heavy drive. You'll pass through or near several well-known areas including the Port Credit waterfront district, downtown Toronto's skyline (visible from certain highway sections), and eventually the Scarborough and North York neighborhoods before reaching Markham's business and residential areas.

Practically speaking, this route involves substantial elevation changes as you navigate the Don Valley's descent and ascent, though nothing dramatically steep. The entire drive is almost exclusively urban and highway-based with minimal rural sections, so expect steady traffic and multiple lane changes depending on time of day. Spring through early fall offers the most pleasant driving conditions, with clear visibility and manageable road conditions, while winter months can present challenges with snow and ice, particularly where the Don Valley Parkway's curves and grades can become treacherous.

Driving Strategy
