The first official weekend of the school summer break is historically one of the busiest periods of the year for Ontario’s three international crossings with the United States. On Saturday, June 27, 2026, the Canada Border Services Agency (CBSA) issued an early-morning travel advisory reminding holiday-makers and cross-border shoppers to expect longer than normal wait-times at the Ambassador Bridge and Windsor–Detroit Tunnel, as well as at Sarnia’s Blue Water Bridge. CBSA spokespersons said traffic volumes typically jump by 20-to-30 percent once classes end, with many families taking advantage of the July 1 (Canada Day) long weekend to visit relatives, stock up on U.S. goods or kick-off cottage vacations. Officers will move to maximum staffing at primary inspection booths; nonetheless, drivers were urged to cross outside peak windows (mid-morning southbound / late-afternoon north-bound) or use lesser-known ports such as the Walpole Island Ferry.

If your trip southbound is only the first leg of a longer journey—or if relatives flying in need additional travel documents—VisaHQ can take the guesswork out of visas and electronic authorizations. Their Canada page (https://www.visahq.com/canada/) walks users through requirements for the United States and more than 200 other destinations, offers real-time status tracking, and provides expert support so paperwork is squared away well before you reach the border.
The Agency also repeated its perennial “know before you go” guidance: have passports ready, fill out ArriveCAN in advance when re-entering, check real-time wait-times on the CBSA website, and declare all purchases—including online orders picked up stateside. Special attention is being paid to travellers accompanied by minors who are not their own children; agents advised carrying notarized consent letters to avoid secondary inspection. From a corporate-mobility perspective, the advisory signals that employee travel times on the critical Detroit–Toronto corridor could be unpredictable over the next six weeks. Mobility managers are encouraged to pad itineraries, book refundable air connections out of DTW or YYZ, and remind assignees of cannabis prohibitions that continue to trip up occasional travellers despite legalization on both sides of the border. Looking ahead, CBSA officials confirmed that additional temporary lanes will open for the FIFA World Cup period in June-July 2026, but said no extra infrastructure is planned for this weekend. Companies moving time-sensitive goods under the Free And Secure Trade (FAST) program were told that commercial lanes remain fully operational and should not be affected by passenger backups.
