The approach of Phase 2 was met with various complaints. A biology professor at the Université de Moncton noted that $200,000–$250,000 worth of pesticide would be required to keep the mosquito population around the city of Moncton from doubling once the gates open. Flood warnings were issued by the provincial Department of Supply and Services for the town of Riverview, warning that high river tides could lead to the flooding of over of sport fields and structures built in low-lying areas; however, they added that the causeway's flood gates were able to descend if required, eliminating the chances of such repercussions from a possible inundation. Residents near the headpond west of the causeway criticized the project, citing the decrease in property values of about 480 homes (by approximately 30 percent, according to the EIA report), the $68 million price tag, unstable ice conditions, and a lower water quality. In spite of legal threats by the Lake Petitcodiac Preservation Association (LAPPA) and various residents, the causeway opened its gates on 14 April 2010, coinciding with the beginning of various studies.
