Narrative:

After departure; while climbing in icing conditions and climb or takeoff thrust selected; we received a 'wing anti ice leak' red EICAS message with associated master warning and triple chimes. I was flying pilot and assumed radio communications; while the captain began running the checklist. During this time; the warning message disappeared and was replaced by 'right wing anti-ice fail; left wing anti-ice fail; right engine thrust fault; and left engine thrust fault'. The original checklist allowed us to turn the anti-ice back on at some point and it continued to work fault free. We elected to divert and wrote up the aircraft. After landing and while writing up the aircraft; the captain relayed a conversation with the bombardier representative that receiving this message is a known issue with the engines at high power settings due to the volume of bleed air available. I heard the word 'normal' used but don't want to put words in anyone's mouth. This is an issue that needs to be worked out. A master warning should never stem from a known issue. We were flying an obstacle departure in icing conditions relying on a system that failed due to a design fault. While we did not notify ATC of an emergency; that fact exists because ATC was informed of the situation and assigned a higher altitude out of icing conditions. A successful outcome was further enhanced by a crew that was able to automatically assign and communicate task assignments immediately upon digestion of the situation. Both of us were relatively new to the aircraft but have extensive experience in other aircraft as well as airline experience. It is still a major problem that a known issue throws us a potential emergency during a high workload phase of flight. This known issue could easily result in an undesirable outcome if replayed by a fatigued or more inexperienced crew.

Title: CL-350 First Officer reported receiving warning messages for anti-ice and engine thrust while climbing through icing conditions.

Narrative: After Departure; while climbing in icing conditions and climb or takeoff thrust selected; we received a 'WING ANTI ICE LEAK' red EICAS message with associated Master Warning and triple chimes. I was flying pilot and assumed radio communications; while the captain began running the checklist. During this time; the warning message disappeared and was replaced by 'R WING ANTI-ICE FAIL; L WING ANTI-ICE FAIL; R ENG THRUST FAULT; and L ENG THRUST FAULT'. The original checklist allowed us to turn the anti-ice back on at some point and it continued to work fault free. We elected to divert and wrote up the aircraft.
