Atrium is a non-bank provider of residential and commercial mortgages that lends in major urban centres in Canada where the stability and liquidity of real estate are high. Atrium's objectives are to provide its shareholders with stable and secure dividends and preserve shareholders' equity by lending within conservative risk parameters.
