Some history sites suggest that the Winnipeg plant located at 770 Dufferin Ave. was turning out four trailers per day by 1972. This may have been the case early in the year, however by mid-year 1972 the Winnipeg plant was only producing about one trailer per day. This was largely due to the local market becoming saturated and compounded with a struggling economy and oil embargo. The photos below indicate that approximately 90 bolers were produced from May 1972 thru July 1972 or approximately one per-day. In 1973 Olecko and partners sold the Boler company to Jim Pattison of Neonex Industries.
