VANCOUVER — In Vancouver’s Mount Pleasant neighbourhood—sandwiched between the creek’s coast and residential towers on the north, and old, mostly single-family character houses on the south—sits an industrial area the city wants to revitalize. The roughly 40-block area hosts a mix of low-rise offices, shops and services, as well as homes and a public park. The city’s vision, though, is to evolve it into an innovation hub with a thriving food and arts scene. AbCellera, once a small biotech with six staff at the University of British Columbia, appears poised to become the area’s anchor tenant, snapping up lots that would eventually total nearly 450,000 square feet of office and laboratory space there.
