SAINT JOHN, N.B. -- You don't have to go far to see cranes, heavy equipment, and other signs of construction in Saint John's city core these days. Several high-profile and large-scale residential developments are now being built in the uptown peninsula amid a surge in demand. Ground has now been broken on a major mixed-income housing development that's been years in the making -- a 48-unit apartment complex called The Wellington in Saint John's city core. "It's been in concept now for probably about three years and, so,within the last month we've began construction on it," Lisa Keenan, the presidentof Saint John Non-Profit Housing."We're putting in a foundation; we're working away on it and hopefully within 18 to 22 months the building will be complete."
