A year after its bid to merge with now-defunct Canadian firm Heenan Blaikie fell through, DLA Piper has found a partner up north in Davis, a 260-lawyer midtier firm based in Vancouver. The combination, effective in April, marks the latest combination of a U.S.-based global firm with a Canadian one.

The tie-up, which Davis partners voted overwhelmingly to approve Wednesday, and DLA Piper's global and Americas boards approved the week before, will bring into the DLA Piper fold seven new offices besides the base in Vancouver, including Calgary, Edmonton, Montreal, Toronto, Tokyo, Whitehorse and Yellowknife—the latter two in Canada's mining-rich provinces in the Yukon and Northwest Territories, respectively. (At 60 and 62 degrees north, the two outposts may well be the most northerly of any Am Law 100 firm.)

The merger should boost DLA Piper's head count to around 4,460 lawyers globally and is the firm's most audacious since May 2011, when it announced that it would formally integrate with DLA Phillips Fox, an alliance partner in Australia. The New Zealand unit of DLA Phillips Fox has now also joined its Australian counterpart and agreed to rebrand under the DLA Piper name, although sibling publication The Asian Lawyer notes the latter will remain financially independent. (DLA Piper itself was formed through a three-way merger of U.S. and U.K. firms in 2005.)
