Please feel free to make suggestions on this topic. Email  [email protected].  There is another timeline dealing with regional history under development 

This is essentially a list of the years when events significantly changed the community that became Mount Dennis, as recorded by European settlers, for better or worse. A history of First Nations in the Humber would be welcomed, as well as information on our industrial past.

A 15th century Wendat village on Black Creek some distance north of here is documented here 

In 1615, Etienne Brule travelled into the Great Lakes basin, seeing all five Great Lakes, and was the first European reported to travel the Humber. His travels triggered the fur trade that would change the face of the continent over the next two hundred years, and change the trading relations of the First Nations peoples.

1791 John Graves Simcoe became the first Lieutenant Governor of newly partitioned Upper Canada . In 1793 he signs a watered down bill to slowly eliminate slavery in Upper Canada, 41 years before the British passed similar gradual elimination legislation for the rest of the Empire.

Returning from the 1793 parliamentary session at Niagara on the Lake, Simcoe travelled through what would become Mount Dennis, renaming the river after the English Humber river. Perhaps now is a good time to revert to the Anishinaabe name, “Cobechenonk” meaning “leave the canoes and go back”. Simcoe decides to build what would become Yonge Street rather than use the Carrying Place Trail as a military road.

Simcoe ordered the lands to be surveyed and granted to settlers. Ship builder John Dennis and brewer John Denison walk to the highest point visible from the Humber and decide to homestead on ‘Mount’ Dennis.

1801 is the earliest gravestone in St John’s Cemetery on the Humber.  The Denison family would move to York (later renamed Toronto), keeping the farmland and becoming extremely wealthy from beer and land development as settlers flock to Upper Canada after the Napoleonic wars. The Dennis family would acquire most of the local Humber Valley land from Weston to the Black Creek.

1812-1814 European Napoleonic Wars fought by proxy in Upper Canada, essentially First Nations vs Americans. First Nations were promised large tracts of land, but are to this day still trying to gain vacant possession. (read about Caledonia land claims )

1850  York Township is incorporated, Humber River to Victoria Park/Scarborough boundary under the ‘Baldwin’ 1849 Municipal Corporations Act. York Township would slowly shrink due to a) annexation by Toronto and b) secession by North York, eventually becoming the City of York and then amalgamated into Toronto with no consultation.

1861  Toronto Street Railroad begins horse drawn street railroads to Weston

1867  Confederation of Canada ( Ontario, Quebec, New Brunswick, Nova Scotia, PEI)

1885 Troops including George Taylor Denison III leave West Toronto Junction on the Canadian Pacific Railway to fight Louis Riel and the Metis. Denison declares Conservatives a “government of land sharks” but fights anyway. Riel is executed and the Metis lands confiscated.

1887  Village of West Toronto Junction incorporated, railways lead to industrialization of the rail corridor from Lake Ontario to Malton.

1891  Dennis Avenue Public School opens

1892  Electrification of the Weston- Lambton line, Toronto Suburban Street Railway  

1895  Four local companies merge to form Canadian Cycle and Motor (CCM), CCM would go on to produce automobiles

1904  Toronto Free Hospital for Consumptives (sanitorium) opens at Buttonwood Farm using obsolete horse drawn streetcars for patient accommodation

1910   First Flight over Toronto at Trethewey Air Field, unrelated fire destroys much of the hospital

1914  Suburban rail line extended to Woodbridge, (now the Runnymede Transmission Corridor); WW1 begins

1917  First X-ray machine at sanitorium

1924  TTC takes over street railway, bus and trolley services begins to York Township

1938  Ruddy Building opens at west Park.  It will soon be gone! Hospitals and Sanitoria for Consumptives Act passed, West Park now has capacity of 600 TB cases. If you think COVID-19 and SARS are bad, imagine 600 patients and no cures.

1944  Three Westlake brothers from Mount Dennis die in D-Day invasion (Memorial at Heroes Lane & Jasper Avenue)

1948  Humber River Conservation Authority formed, merged into Toronto and Region Conservation Authority (TRCA) in 1956

1954  Hurricane Hazel floods area, 81 die in the region.    West Park piggery and children’s playground in the valley are destroyed.  Fourteen bodies retrieved from Black Creek.

1961  Mount Dennis Library opens at Weston and Eglinton. Previously the Library operated out of the Legion and other temporary sites.

1970  Eglinton Avenue opens from Weston Rd to Royal York, now only 360 annual TB cases but 150 still in chronic care. Antibiotics have arrived!

1971 Conservative Premier Bill Davis cancels the Richview Expressway. Although the expressway would have razed much of Mount Dennis, the cancellation led to a situation where the high rises approved to border it were allowed to be constructed, but the business district collapsed, leading to unemployment and poverty.

1974  Consumptives Act repealed, hospital becomes a chronic care center named West Park Hospital

1983  CCM bankruptcy

1988  Frances Nunziata first elected to York council, she becomes York Mayor in 1994

2005  KODAK closes Mount Dennis site

2012  Construction FINALLY resumes on Eglinton, now an LRT but 17 years after Conservatives cancelled the first try.  Construction delayed due to complications caused by earlier tunnels being filled with concrete.

2013 MD Library reopens after $4M makeover; flooding causes tens of millions of dollars damage to hundreds of homes in the area

2019 West Park begins redevelopment, existing buildings to be replaced

2020 Province announces plans to extend LRT to the airport, a bridge to be built over the Humber
