Comments On November 15th, a strong frontal system passed through Ontario and Quebec. The system brought an array of hazardous weather conditions: An EF1 tornado touched down near Georgetown; there were four confirmed downbursts events (Dunnville, New Dundee, Ingersoll, Port Burwell) with wind speeds ranging from 115-135 km/hr; strong winds across much of northeastern and southern Ontario (Port Colborne, for example, recorded maximum wind speeds of 132 km/hr with 10 consecutive hours of winds over 80 km/hr); and a significant seiche in Lake Erie (4 m sea level difference between Toledo, Ohio, and Buffalo, New York). As a result, this system generated widespread damage across Ontario and into Quebec - southwestern Ontario was the most impacted. By the early evening of November 15th, over 1 million individuals were without power in Ontario, Quebec, and the United States. Hydro One reported over 542,000 customers that were affected and over 500 downed hydro poles; power was still not fully restored to all customers by November 19th.

Comments The winter of 2018 was one of the coldest on record, which created a very strong icepack throughout the Grand River watershed in Ontario. In addition to this, temperature drops led to the formation of frazil ice – heavy slush in rivers. On February 19th, 40-60 mm of rain fell. The combination of frazil ice, ice jams, 40-60 mm of rain, and 50-70mm of melting snowpack caused the water levels of the Grand River to rise rapidly. Ice jams tended to form in Cambridge, Brantford and Cayuga – in Cambridge the ice jam measured 5 km upstream. The Grand River Conservation Authority issued flood warnings for several communities including Brantford, Cambridge, North Dumfries and Brant County. The first warning was issued on February 16th but by February 18th a warning was issued for the entire watershed. Up to 2,200 homes and 4,900 residents were impacted by an evacuation order.

Comments Southern Ontario, ON, December 21, 2013 to January 1, 2014. A severe storm brought freezing rain and damaging ice accumulation across a large area of southern Ontario. According to Environment Canada, the epicentre of the freezing rain was in southern Ontario along the north shore of Lake Ontario, including the Greater Toronto Area, where ice accumulation reached up to 30 mm. The impact of the ice storm on these municipalities and conservation authorities was further exacerbated by freezing temperatures. The ice storm had serious impacts. In its aftermath, as many as 830,000 hydro customers (2,490,000 individuals) across Southern Ontario were without power for several days. Downed trees, broken branches, and downed wires resulting from ice accumulation posed serious public health and safety risks, as well as transportation network problems. Due to widespread power outages and freezing temperatures, municipalities activated emergency plans to open warming centres and canvassed homes of vulnerable residents to ensure their safety. Power was restored to most residences and businesses by January 1, 2014. Response and recovery activities began at the time of the event. The ice storm significantly impacted some of Canada’s largest and most densely populated urban municipalities. Municipalities, provincial ministries and non-governmental organizations such as the Red Cross all acted to respond to the ice storm. Ontario determined that the impacts of the storm were severe enough to warrant implementation of an Ice Storm Assistance Program to help municipalities and conservation authorities with emergency response and recovery costs. Two deaths were attributed to the storm due to carbon monoxide poisoning from improperly ventilated generators and heaters. *Note: A request for federal assistance through the DFAA program has been made; however, no payments have yet been issued.

Comments On February 2nd, a citizen of Windsor (case 1) became seriously ill with a virulent form of hemorrhagic smallpox. The doctors did not initially consider smallpox until other individuals in close contact with the initial patient became sick. Case 1 died of smallpox on February 11th. Cases 2, 3, and 4 did not present with symptoms until February 20th and 24th. However, by the time smallpox was recognized, it had already spread in Windsor and neighbouring communities including Detroit. On the evening of February 23rd, the Local Board of Health made the decision to quarantine those who were sick and their families, and to vaccinate the entire population of the city (70,000). The majority of physicians in the entire region were mobilized within 30 minutes, and vaccines were being given by the next morning. Within 6 days, 95% of the population was successfully vaccinated. Out of 67 individuals who became ill with smallpox, 32 died (a fatality rate of 48%). Not a single person who was vaccinated died of smallpox.

Place: Cochrane, Ontario Injured / Infected: 823
Event Date: March 19, 1923 Evacuated: Unknown
Estimated Total Cost: Unknown
Comments In the early 1920s, the primary water supply for the community of Cochrane, ON, was natural springs. As the community grew, the springs were no longer able to meet the community requirements (such as fire suppression), therefore pumps were also connected to Spring Lake. The need for an improved water supply was identified in the summer of 1921, but no improvements were made. Typically, Spring Lake would sit higher than other waterways; however, water was needed from the lake during the fall and winter of 1922-1923. With this, the water level was lowered to the point that it was below the level of surrounding waterways which were contaminated with sewage. On March 11, 1923, the Provincial Sanitary Engineer determined that it was imperative to install a chlorination device, and oversaw its installation on March 15th. However, the contamination of the water supply had already infected residents and the first cases of typhoid were recorded within days. By April 3rd, there were 600 cases and 12 deaths which quickly grew to 823 cases and 59 deaths.

Estimated Total Cost: Unknown
Comments In June of 1912, a typhoid epidemic began in Ottawa. Following a serious epidemic in the previous year, recommendations were made to improve the water supply including adding more hypochlorite of lime as a temporary measure, the construction of a new intake pipe as well as the construction of a proper filtration plant. The construction of a new intake pipe was finished and in use by April 13th, 1912. Two weeks later, water tests continued to show water contamination because the old intake pipe (which was in poor condition) was still being used. Relatively little action had taken place and in June, 10 cases of typhoid were reported. A month later, there were over 1,000 cases. The number of infections diminished by the end of September. In total, 1,378 individuals had been infected and 91 died as a result.
