Canada\'s gross domestic product dipped by 0.1 percent in November, largely because of decreased energy output, Statistics Canada said Tuesday. Oil and gas extraction declined 2.5 percent in November, particularly in the output of crude petroleum, the report said. \"Decreases were also recorded in wholesale trade, finance and insurance and construction,\" StatsCan said. \"Gains were posted in manufacturing, retail trade, accommodation and food services, professional services, and real estate agents and brokers.\" Manufacturing increased 0.6 percent, the third consecutive monthly gain. Growth was mainly based in the production of durable goods. Because of unseasonably warm weather, demand for electricity was down, contributing to a 0.6 percent decline in the utilities sector, the report said.
