The amount of new building permits across the country reached $6.4 billion in July, down from $6.6 billion one month earlier, Statistics Canada reported Wednesday.
"The decrease in July was a result of declines in both the residential and non-residential sectors," Statistics Canada said.
Home building permits were off 2.4 per cent while business construction permits fell by 4.3 per cent in July versus June.
Statistics Canada does not usually speculate as to the underlying reasons for changes in the value of the country's building permits.
But Canada's economy did slow to two per cent in the second quarter of 2010 compared to a gain in gross domestic product (GDP) of 5.8 per cent in the January-to-March period.
The construction sectors in Alberta and Newfoundland and Labrador exhibited the largest declines in July.
Newfoundland and Labrador saw the value of building permits tumble by 62 per cent in July, led by an 80 per cent decline in business permits.
Alberta, which has seen overall economic activity in the province slow, experienced a 19 per cent drop in building permits. The value of business building permits in the province fell by nearly 40 per cent in the same month.
