Saw this on another forum. Sorry if it was already posted.

Judging from the pictures, with the snow/ice on the ground... I wonder if proper de-icing took place. Always a concern for any plane, but the CRJ's super-critical wing design makes it even more important for proper de-ice/anti-ice to be applied...
Glad everyone survived...

This was posted by someone on 2/14 on the other website regarding this thread:
If it was icing, it's ironic that Bombardier issued this message just YESTERDAY.

The purpose of this AOM is to increase flight crew awareness of safe take-off practices when operating CRJ aircraft. Flight crew and support staff should be made aware of the rationales for specific take-off procedures and the potential consequences for not following these procedures.
Recently, on a positioning flight with flight crew only onboard, a CRJ100 experienced an uncommanded roll immediately after lift-off. The Stall Protection System (SPS) stick shaker and stick pusher activated and a combination of the SPS activation and flight crew actions resulted in a successful recovery of the aircraft. The flight was then continued to its destination.

The flight was then continued to its destination.
This event is currently under investigation by the host country local authorities; we are therefore limited in the amount of information that we can release. The Transportation Safety Board of Canada and Bombardier are assisting with the investigation. Weather conditions at the time of take-off included moderate snow, which contributed to the
event. The occurrence aircraft was de-iced and anti-iced prior to take-off and appropriate holdover times appear to have been respected. However, wing anti-ice was “NOT” selected for
take-off, contrary to the direction provided in the Aircraft Flight Manual. In addition, the aircraft rotation rate was considerably beyond the normal 2.5 to 3 degrees per second recommended
rate.
During post-occurrence analysis of the Flight Data Recorder, an additional four SPS events were found on the same aircraft, where the stick shaker activated immediately after lift-off.
The following take-off guidance must be respected for every flight:
Pre-take-off preparations shall include:

The following take-off guidance must be respected for every flight:
Pre-take-off preparations shall include:
•
Perform accurate weight and balance calculations.
•
Select the take-off speeds accurately including corrections if appropriate.
•
Ensure the wings and airframe are clean (de-ice / anti-ice as required – respect
holdover times).
Ensure that proper take-off thrust and trims are set.
Take-off procedures (All Engine Operation - AEO):
Ensure that wing anti-ice is selected prior to initiation of the take-off roll, if required.
•
At Vr rotate smoothly towards the target pitch attitude in one continuous motion
(As a guide: Maximum recommended pitch rate of 3o per second on the CRJ200)
Adjust pitch as required to accelerate to a speed of not less than V2 + 10 KIAS.
•
The flight director guidance represents an initial target for rotation only.
•
Pilots must transition to speed control immediately after rotation.
