Canada's manufacturing sector contracted for a sixth straight month in July as tariffs undercut trade with the United States and spurred firms to reduce inventory as well as staffing levels, data on Friday showed. The S&P Global Canada Manufacturing Purchasing Managers' Index (PMI) edged up to 46.1 in July from 45.6 in June but remained well below the 50 no-change threshold. A level below 50 indicates contraction in the sector. The PMI has posted sub-50 readings since February.
