I am no expert on blended Canadian whisky but I do not believe that these are very collectable
They may be from 1949 and 1957 but usually the attractiveness for whisky collectors is due to a combination of the fact that it is Scotch, the brand and the age (unless it is a pre-Prohibition or Prohibition US bottle)
Hence a Dewar’s from the late 1940s might be worth $125 or so. A single malt from the 1940s would be worth considerably more. However neither of these bottles are a collectable brand nor are they Scotch.
Am sure there are interested parties out there - be patient...but would not expect to get a whole lot for them. You might re-name the thread Corby/Schenley to draw people's attention to it
