CRJ100/200 has been flown in North America for the last 15 years or so and with all the very severe winters they have, I believe not one CRJ has been lost due to icing. For me that speaks volumes about good training, knowledge and SOP's.
There are also many Challenger 600 series planes flying about all over the world with some very professional corporate operators who have no problems operating this popular type.
It all comes back to good training, knowledge and SOP's!
