there are four, Metrotown, Edmonds, Brentwood and Lougheed which is getting a boost from the Burquitlam/West Coquitlam developments going up. Lougheed is adding 23 towers at the mall, plus Lougheed Village is going to be adding 3 new towers to its site, I think its 46 storeys for the tallest there, it will be west of the mall in the middle of the current cluster.
