However, the OECD again raised a red flag about the rapid increase in house prices in Canada and other countries including Australia, Sweden and the United Kingdom.

"As past experience has shown, a rapid rise of house prices can be a precursor of an economic downturn," it said.

The OECD works with the governments of 35 member countries, including Canada, and major non-member countries including China, India and Brazil to collect data and analyze economic trends around the world.

The modest pickup in global growth in 2017-18 reflects the effect of ongoing and projected fiscal measures, notably in China and the U.S., and initiatives in other economies such as Canada, the report says.

"These are expected to catalyse private economic activity and push up global demand."

"Exiting the low-growth trap depends on the joint impact of macroeconomic, structural and trade policy choices, as well as on concerted and effective implementation of existing initiatives."

The OECD report said the U.S. and Canada are projected to lead the Group of Seven countries in economic growth this year, with the next highest G7 country being Germany at 1.8 per cent GDP growth.

Next year, the U.S. economy is projected to grow by 2.8 per cent and Canada's is expected to expand by 2.2 per cent, ahead of the other G7 countries. Global economic growth for 2018 is forecast to be 3.6 per cent.

In its previous report issued in November, the OECD estimated Canada's economic growth for 2016 would be 1.2 per cent, but that was upgraded Tuesday to 1.4 per cent, in line with what Statistics Canada reported last week.
