Narrative: On Jan. 2015 a Challenger 300 departed ZZZ for ZZZ1 at XA20 local time. No passengers were on board. We had received the weather; I believe it was information S; 32013G20KT 10SM CLR 09/M06 A3027. It also included hazardous winds had been reported and we had heard earlier over ATC that a Hawker had reported windshear loss of 15KTS. I had briefed earlier that if we got a windshear alert that an option would be to climb out and ask for a left downwind to RWY 32; but generally do not use that runway due to its shorter length and pavement conditions. We were cleared for the visual at 6000 MSL. I then set the ASEL to 3000 MSL while still on autopilot. At altitude captured was fully configured; I disconnected the autopilot as I was making the turn to final. We did not receive a hand off to tower until we were turning inbound when [SIC] prompted ATC to switch to tower and were cleared to land. Winds were very gusty. I had set up for the visual RWY26 with a 4 mile final to give me a little extra room to get aligned. I had a little extra power in as I made the turn to final to maintain speed in the gusty conditions and was working the speed down on final as I was descending but it was fluctuating with the gusts and did not want to get too slow. I had quite a bit of left rudder in to counter balance the crab into the wind but I felt I was in control of the aircraft to touchdown. Upon touching down on the runway we caught a gust that brought the right wing up. As I was veering toward the left side of the runway; I was calling to hand the control yoke over to [SIC] so I could utilize the tiller. With the direction angle on the runway and the speed I felt an abrupt right rudder could have side loaded the main and scraped a wing. Once I recognized that I was going to make contact with the grass; I tried to maintain a straight path and bring the aircraft to a stop while avoiding obstacles on the taxiways. I landed at the markers and exited before taxiway K. We came to a stop just after taxiway J. Touchdown was recorded at XA43 local via the FMS. Tower immediately asked if we were okay and if we needed assistance; fire or a tug. We were monitoring the tower and contacting our maintenance personnel to come out to inspect before we did anything. We then shut down the engines and waited for our maintenance to come out with tugs. After they inspected the outside we opened the door and walked around the aircraft. We determined that we would attempt to taxi out of the grass if possible. At that point the Fire personnel arrived and wanted to know if we needed assistance. We declined. We were able to do a normal start and taxi from the grass to the taxiway and then to our hangar. Steering; braking and taxiing all seemed normal. There was minor damage to the left flap and we hit one taxi light. Event was caused by failure to maintain directional control on centerline in gusty conditions. I had made this landing many times over the past 4 years as ZZZ1 is our home base. Options could have been a go around or utilizing RWY 32; but given I had already touchdown; the biggest factor was maintaining directional control.


Second narrative: Aircraft drifted left of center line prior to touchdown. As the main gear touched down a gust raised the right wing. I looked over to check that the spoilers were deployed. Captain commanded me to hold the tops; which I did as the aircraft left the runway near taxiway K. The aircraft continued southwest between runway 26 and taxiway I and came to a stop about 100 feet after crossing taxiway J.


Synopsis: CL30 flight crew reported losing directional control of the aircraft during landing in gusty wind conditions. Aircraft left the runway and struck a runway light; and post flight inspection revealed minor damage to the left flap.
