(Corrects to clarify quote in second paragraph with context in parentheses) TORONTO, March 23 (Reuters) - The Bank of Canada has anecdotal evidence and limited data that shows investment activity and home flipping is rising in certain Canadian housing markets, a deputy governor told Reuters on Tuesday. In some cities “we have data on investment purpose, versus living-in purpose ... we have data on how long before it went back on the market. Those things ... they (would) indicate a lot more investment activity, a lot more flipping,” deputy governor Toni Gravelle said in an interview. The central bank is doing a lot of analysis on housing, some of which may be ready in time for the Monetary Policy Report in April, but is likely to be more of a focus in the May Financial System Review, Gravelle said.
