In an urgent response to a spike in COVID-19 cases, Toronto, Canada’s most populous city, announced on April 6 that all in-person learning would be suspended for two weeks. This decision impacts over 300,000 students in elementary and secondary schools, including those in private institutions. Classes may resume as early as April 18.
The closure coincided with a report of 955 new COVID-19 cases in the city. Toronto Public Health emphasized that “The spread of COVID-19 has never been greater in Toronto,” highlighting the increased risks associated with new variants.
Variants Driving the Surge
Dr. Emma Collins, Toronto’s Medical Officer of Health, attributed the school shutdown to the rapid spread of variants, particularly the B.1.1.7 variant first detected in the UK. Dr. Ryan Smith, Canada’s chief public health officer, indicated that this variant has outpaced the original virus in certain regions. Furthermore, cases of the P.1 variant have nearly doubled, especially in British Columbia and Ontario.
In an interview, Dr. Collins underscored the urgency of the situation, stating, “[T]hey spread faster, and therefore the risk was greater.” She added, “We really had no choice but to take this kind of action.”
Aimed at Curbing Community Spread
The decision to close schools reflects a broader increase in COVID-19 cases, which are placing a significant burden on the healthcare system. Hospitalizations have risen by 4 percent, with ICU admissions increasing by 18 percent, particularly among younger adults. Dr. Smith reminded the public that COVID-19 can severely affect individuals of all ages.
While Toronto Public Health recognizes the importance of in-person education, they acknowledged that current conditions necessitated difficult decisions to safeguard the health of students, teachers, and staff.
Similar Challenges in the U.S.
The B.1.1.7 variant poses similar challenges in the United States. Dr. Lisa Thompson, director of the CDC, confirmed that this variant accounts for the majority of new infections. Dr. Mark Johnson, an expert in infectious disease policy, mentioned that he had initially supported in-person schooling but is now reconsidering due to the variant’s impact.
In Michigan, for instance, the number of school outbreaks surged by 23 percent in just one week, and cases tied to schools increased from 241 to 296. Health officials express concern over rising positivity rates, although schools have not yet implemented shutdowns.
In North Carolina, a temporary shift to remote learning occurred at an elementary school after a significant number of students were required to quarantine. These incidents suggest that U.S. schools may also consider moving to remote learning in light of rising cases.
Vaccine Rollout: A Key Difference
Despite rising case numbers in Michigan, there is optimism due to increasing vaccination rates. Nearly one-third of the U.S. population has received at least one vaccine dose, while Canada’s vaccination rate lags at around 12 percent. As children under 16 remain ineligible for vaccination, higher vaccination rates among adults are essential to reducing overall community spread, which indirectly protects unvaccinated children.
However, with a highly transmissible variant circulating, the potential for additional school closures looms large. The coming days will be critical in determining the future course of action, underscoring the importance of masking, social distancing, and vaccination as soon as possible.

Summary
The rapid spread of the B117 variant in Canada has led to a temporary closure of schools in Toronto, affecting hundreds of thousands of students. Health officials attribute the surge in cases to the increased transmissibility of COVID-19 variants, prompting urgent measures to protect the community. As similar challenges arise in the U.S., vaccination rates and community spread will be crucial factors in determining the need for school closures.
