Calgary-based Middlefield Group has launched a pair of actively managed ETFs by converting two of its closed-end mutual funds, the investment manager announced Tuesday.

Middlefield Healthcare & Life Sciences Dividend Fund and REIT INDEXPLUS Income Fund began trading on the Toronto Stock Exchange on Tuesday as Middlefield Healthcare & Life Sciences ETF (ticker symbol: LS) and REIT INDEXPLUS ETF (ticker symbol: IDR), respectively.

The conversions to ETFs were not taxable events for unitholders.
