Gooderham and Worts has a long reputation for making spirts now the old distillery is part of the distillery district historical area in Toronto please see link. http://www.thedistillerydistrict.com/
An exceptional product was produced and a sealed bottle would be of interest to a collector. Barring in mind that Canadian Whiskey is blend and for that reason something bottled in 1961 should taste the same as if it was made yesturday. For my self I've only seen one bottle of the Centennial Run and really would need to see a picture of the bottle/content/case to even harbor and estimate. If you could send pictures this would help.
