(Adds details on tenant movement)

TORONTO/MONTREAL, Feb 26 (Reuters) - Dream Office Real Estate Investment Trust is working with TD Bank and CBRE to sell half of its stake in Toronto's Scotia Plaza, Canada's second tallest office building, according to two sources familiar with the matter.
The potential sale comes about four years after Dream Office REIT, then called Dundee REIT, acquired two-thirds of the 2 million square-foot Scotia Plaza complex. H&R REIT bought the rest of the stake at the time. The C$1.3 billion ($961.68 million) deal marked the highest price ever paid for a Canadian office building.
Dream Office is now looking to sell half its stake, leaving Scotia Plaza potentially in the hands of three different owners with equal positions, according to the sources, who requested anonymity because the matter is not yet public.
Under a possible arrangement, Dream could seek to retain management control, one of the sources said, adding that it would depend on the outcome of the final deal terms with the buyer.
Strong interest is expected from foreign buyers and Canadian pension funds, the sources said.
However, Scotia Plaza is facing the prospect of jump in its vacancy rate, now about 2 percent, because of tenant migrations, according to a real estate industry source, who asked not to be identified because of the sensitivity of the issue.
Borden Ladner Gervais, one of Canada's largest law firms, confirmed on Friday it is planning to move out of Scotia Plaza this year.
The news comes as a significantly weaker Canadian dollar is attracting increasing attention from global investors seeking an alternative to tumultuous equity markets.
Scotia Plaza is in the midst of significant renovations in recent months, though it is not clear if they are tied to the potential sale.
As part of a recently announced strategic plan, Dream Office said it is looking to sell non-core assets worth C$1.2 billion over the next three years.
Dream Office Chief Executive Jane Gavan did not immediately respond to an email requesting comment. TD declined comment, and CBRE did not immediately respond to a request for comment.
Dream Office shares lost 31 percent of their value last year, largely due to concerns about its large exposure to the Alberta market, which has been hit by the oil price collapse.
This year the stock has gained nearly 14 percent, helped by the announcement about selling assets. It was up 2.2 percent on Friday.
