Interesting photo, and I thank you for drawing it to my attention.
Given that this car did not appear in Shawinigan Chemical listings until 1946, despite an 8/1933 built date, I think we’ll find that it had a previous identity as a U.S. car (possibly GATX) — which would explain why the capacity is noted in U.S. gallons, rather than the Canadian standard of Imperial gallons (BTW, the ratio is roughly 6 U.S. gallons to 5 Imperial gallons, and for many years this was the conversion ratio used on stencilled capacities).
As an aside, I can’t imagine that many tank cars were built in 1933, especially aluminum tanks...

The car is listed in the Canadian Section of the tariff so is listed in
imperial gallons. The car is stencilled in US gallons for some reason. The dome
is closer to 216 US gallons.

posting this I see the end lettering says 8,153 gallons. I was looking at the
1955 tank car tariff. I guess the car number got reused or the tank itself was

riveting around it, plus the shape) was 180 gallons. Aluminum tank with heater

Info on the
company from the ‘net:
Carbide Company, forerunner of Shawinigan Chemicals Limited, was established
in 1901 by Thomas Leopold "Carbide" Willson, who invented the carbide
manufacturing process in 1892. The plant was sited at Shawinigan Falls,
Quebec, in order to take advantage of surplus electric power produced by
Shawinigan Water and Power Company, itself established in 1898. In 1909 SWPC
gained a controlling interest in Shawinigan Carbide Company and in other
Willson companies, and in 1911 reorganized them as the Canada Carbide Company.
In 1915 SWPC established the Canadian Electro Products Company to manufacture
acetone and other products for the British war effort. With the loss of its
markets in 1918, the new company directed its research facilities to the
development of chemicals for civilian consumption; thenceforth the company and
its successors based their production heavily on original research. In 1927
Canadian Electro Products and Canada Carbide Company were amalgamated as
Shawinigan Chemicals Limited.”
