CanaData is expecting monthly housing starts in the second half of 2008 to average well below their level in the first half (227,000 units). Nevertheless, because starts were so strong at the start of this year, the forecast for all of 2008 has been revised slightly upwards to 212,500 units from 210,000 units. The official annual figure in 2007 was 228,000 units, according to CMHC. For 2009 and 2010, CanaData is dropping its forecasts by 5,000 units in each year to 190,000 units and 200,000 units respectively.
