INTRODUCTION
The production of gypsum is one of th3 oldest industries in Canda, and in
point of gypsum output Canada ranJis third among the countries of the world.
Gypsum was discovered in the Maritime Provinces at a very early:date, but
there is no authentic record..of production until about 1822, when gypsum was mined
on a small scale in Ontario. Since.then the production has grown slowly but stead-
ily to more than a million tons. In 1928 the output was 1,205,846 short tons,
valued at $3,622,007.
Nova Scotia, New Brunswick, and Ontario, for the early years, were the pro-
ducing provinces. Manitoba entered the field in 1901, and 10 years later (1911)
active operations were started in British Columbia.
At present large quantities of crude gypsum are being shipped from the Mar-
itime Provinces into the United States to be calcined and further manufactured.
At the same time, Canada is purchasing from the Unitee States plaster and other
gypsum manufactures for her own needs.' Domestic pr.duotion of manufactured gyp-
sum products, however, I.s again on the increase,. and smaller quantities of these
products are now being imported into Canada; the reason for this condition, it
is claimed, is that up. to the present there has not been demand enough to warrant
the erection of additional mills in' tha part of. the country. It may be noted,
however, that most of the larger producers of crude gypsum are owned or controlled
by American capital, and- that the phenomenal growth of the exports of Canadian
crude gypsum is due to the increasing demand of plants strategically situated along
the northern Atlantic seaboard.
For the finer grades of white plaster, such as dental plaster, for which
the Nova Scotia rock is admirably suited, and for all grades of finishing plasters,
there seems to oe a rapidly growing Canadian market. The increased demand for
fireproof buildIn s and the extension of building operations throughout eastern
Canada have increased the demand -for gypsum plasters and other gypsum building
materials. In -rder to me;t this demand, new plants have been erected and exist-
ing ones enlarge- and modernized. Increased railroad facilities have contributed
greatly to this end.
The Principal producing centers in the ritimc Pro inces are the following:
