Thunder Bay has the dubious distinction of having the second lowest apartment vacancy rate in the country.Canada Mortgage and Housing Corporation pegs the vacancy rate in the city in October at 1.1 per cent. It's a statistic that concerns Saku Pinta of the Lakehead Social Planning Council. He says it means low income people in the city will be feeling the pressure since they are already struggling to find affordable housing and low rates will help to push rents much higher.
