Winnipeg never had a channel 2, you were probably getting Vancouver! (Sporadic-E favors distances of about 1,000 miles).
TV DX by Es is still possible, though there are far fewer stations on channels 2 to 6 to DX (most lowband stations chose to spend their digital future on UHF or highband channels). The poor multipath tolerance of DTV also makes it more difficult for a DTV signal to be decoded when it is coming in by Es.
