Harold Fisher was the 36th mayor of Ottawa, from 1917 to 1920. Ottawa residents will recognize his name from Fisher Avenue, Fisher Park and Fisher Park High School.
The Civic Hospital visible from the geocache location was built by Harold Fisher, and is the oldest major health center in Ottawa. When Ottawa was devastated by the Spanish flu during Fisher's tenure as mayor, Fisher started to push for a new hospital. His political enemies disliked the un-central location of the hospital (far away in the farmer's fields surrounding Ottawa) and named the plan "Fisher's Folly". The City of Ottawa bought the farmland for ~$70K. Today, the Civic is the hospital closest to Parliament Hill.
In 1943, Dutch princess Juliana, living in Ottawa as a safe haven from the second world war, gave birth to her daughter Margriet at the Civic, on a floor temporarily declared "extraterritorial" to Canada by the parliament, so Margriet could be born with only Dutch citizenship. In 2005, I gave birth to my son in the Civic, however the floor was not declared "extraterritorial" so that my son can claim both Dutch as Canadian citizenship.
After the first geocache disappeared, we placed the second cache on April 10, 2016 in a spot nearby.
