McLeod Young Weir

McLeod, Young, Weir & Co. Limited, and after 1977, McLeod Young Weir Limited, was a Canadian investment brokerage that operated from 1921 to 1988. The firm grew to become one of the country's largest brokerage houses and provided services including underwriting, stock and bond trading and distributing, leasing, private placements, and mortgage financing. McLeod Young Weir had international offices in England, France, and the United States and owned seats on the Toronto, Montreal, Vancouver, Alberta, Winnipeg, and Midwest stock exchanges.

In 1987, the Ontario government amended its regulations to allow banks to own brokerages outright. Consequently, in 1988, the firm was acquired by the Bank of Nova Scotia for $419 million and renamed ScotiaMcLeod. In 1999, the firm was renamed Scotia Capital Inc., while the name ScotiaMcLeod was given to its retail brokerage division.
