A new report says Vancouver's inadequate public transit and lack of affordable housing may hinder the city's ability to attract labour and business investment.

The Greater Vancouver Board of Trade released a scorecard today prepared by the Conference Board of Canada that rates the city ninth among big international cities in terms of key economic and social indicators.

The report says Vancouver ranks ninth in the economic category and seventh in the social category, but housing and public transit hurt the city's liveability ranking and could be hurdles for attracting future investment.

The report says other challenges facing British Columbia's largest city include a low proportion of 25 to 34 year-olds, low productivity levels, land scarcity and high marginal tax rates.

Singapore received the scorecard's top marks, while Miami finished last in 20th place.

Other Canadian cities ranked by in the report include: Calgary in fourth place, Toronto in 10th, Montreal in 14th, and Halifax in 16th.
