The Aircraft Rescue and Fire Fighting (ARFF) unit responded, and Runway 15/33 was closed via NOTAM. The aircraft was pushed off the runway and Runway 15/33 re-opened at 2035Z. The shift manager was notified.
UPDATE: TSB Report #A22O0015: C-GZQT, a Cirrus SR22 being operated by ITPS Canada Ltd. as SA29, was on a training flight in the circuit for Runway 33 with three pilots on board; there was an instructor and a student occupying the front seats. During a normal landing, the aircraft was allowed to slow down unintentionally during the flare, at approximately 5-10 feet AGL. The student attempted to correct by adding power, but moved the control stick in their left hand, mistaking it for the throttle. This resulted in the aircraft pitching down rapidly and contacting the runway, causing the nose wheel assembly to become detached from the aircraft. The instructor pilot intervened during this sequence, and landed the aircraft on the remaining runway. The aircraft came to rest on its nose. There were no injuries.

An Government Of Canada, Department Of National Defence Beech B350 (NSTAR2) from Trenton, ON (CYTR) to Thunder Bay, ON (CYQT) left the runway during its landing procedure on Runway 25. The aircraft came to rest approximately 200 feet south of the runway edge.

During landing, a privately registered Piper PA-46-600TP, on a flight to Stratford, ON (CYSA), went off the end of Runway 17 at CYSA, causing damage to the aircraft.
UPDATE: Aviation Incident Report #17507: A privately registered Piper PA-46-600TP on a flight to Stratford, ON (CYSA) was landing on Runway 17. It appeared that the directional control was lost and the aircraft exited the runway to the right-side. The aircraft struck an abbreviated precision approach path indicator (APAPI) light box and continued travelling across the graded area, and came to rest perpendicular to the runway edge. Weather conditions were VFR, with winds from the south and less than 8 knots. The runway was 95% bare and dry. Runways were closed for several hours.
UPDATE: TSB Report #A22O0013: A privately registered Piper PA-46-600TP was on a visual flight rules flight from Kitchener/Waterloo, ON (CYKF) to the Stratford, ON (CYSA) with the pilot as sole occupant. During the landing roll on Runway 17, the pilot felt the aircraft swerving and attempted a correction before deciding to reject the landing. After they added power for the go-around, the right main wheel entered the snowbank beside the runway, causing the aircraft to exit the runway surface into an area of undisturbed snow. The aircraft collided with some airport signage before the nose wheel sheared off. The aircraft came to a stop upright in a snow covered area beside the runway. The pilot exited the aircraft uninjured, the aircraft had been damaged significantly. The propeller was destroyed, and there was damage to the wing, cowling, and engine mounts. The ELT was activated during the runway excursion.

A privately registered Cessna 150G from Nixon, ON (CNX8) to Nixon, ON (CNX8), was flying locally in the Nixon area, experienced an engine failure with a forced landing, then crashed 1 1/2 NM west north-west (WNW) from the airfield.
UPDATE: TSB Report #A22O0005: At 1620 Eastern Standard Time, a privately-owned Cessna 150G departed from Nixon, ON (CNX8) on a local visual flight rules (VFR) flight. Upon return, the pilot positioned the aircraft on final for Runway 12 at CNX8. Shortly after commencing the final approach, the aircraft experienced a power loss. The pilot verified the engine instruments, which were all indicating normal. The pilot recognized that they would be unable to reach the runway, so elected to carry out a forced approach in a nearby farmers field. The aircrafts main landing gear touched down first, followed by the nose wheel. When the nose wheel contacted the rough terrain, it broke off and the aircraft flipped over and came to rest inverted. The pilot was able to egress from the aircraft with minor injuries. There was no post-crash fire. The aircraft suffered substantial damage.

The terminal pointed out a Pacific Professional Flight Centre Ltd. Cessna 172M (C-GIFM) from Calgary/Springbank, AB (CYBW) to Calgary/Springbank, AB (CYBW) was indicating "unfamiliar" and on a heading of 060. On initial contact, the tower asked if they had the airport in sight. The aircraft then started a left turn, in the opposite direction, to the north ghost route, with a Calgary Flying Club Cessna 172N (C-GYVJ) at a distance of 2 miles in the opposite direction. The tower turned C-GIFM south, instructed them to descend, and advised the terminal, who turned C-GYVJ north to avoid conflict. The aircraft came within 1.1 miles of each other.

Diefenbaker, SK (CYXE) came in close proximity to the west of Regina, SK (CYQR). APLO41 departed CYMJ, northbound, and was maintaining 6000 ft for IFR traffic. C-FMTF departed CYQR, VFR, and proceeded northwest (NW) at 6500 ft. The controller passed C-FMTF as traffic information to APLO41, who reported having a visual. C-FMTF was observed to slowly descend to as low as 6100 ft and APLO41 descended to avoid the VFR traffic. The aircraft passed at approximately 1/2 mile and 200 ft. No impact to operations.

A Chartright Air Bombardier BD-100-1A10 (HRT381) from Calgary Intl, AB (CYYC) to Scottsdale, AZ (KSDL) was in the climb with a clearance to FL330. The controller queried the pilot when the aircraft was observed to be continuing their climb through FL330. HRT381 advised they were correcting and would descend back down. Traffic was a Jazz Bombardier CL-600-2D24 (JZA8191) from Regina Intl, SK (CYQR) to Vancouver Intl, BC (CYVR) who was passed as traffic and came within 4.9NM laterally and 500 feet vertically of HRT381.

An assessment of the aircraft was made by the pilot and the maintenance organization, and no damage noted.

The flight service station (FSS) noticed the apron floodlights and tower beacon turning on, by themselves, while the lighting panel was showing them as "off". The lighting panel became unserviceable (u/s) about 30 seconds later and was showing "Comms Lost". The panel came back and was serviceable within 2 minutes. This happened a second time within 5 to 6 minutes. The FSS called the help desk. They advised that the electrician was trying to troubleshoot the issue the FSS had in the morning but forgot to call the FSS to advise. The electrician stopped the maintenance and advised they will call the FSS to coordinate maintenance when there was less traffic. No impact to operations.

The pilot of an Excel Flight Training Piper PA-23-250 (C-FVIY) from Lethbridge, AB (CYQL) to Swift Current, SK (CYYN) reported that a door came open during level flight level, while en route. The aircraft returned to CYQL without incident. No impact to operations.

A Moncton Flight College Piper PA-44-180 (C-FZKH) from Moncton/Romeo Leblanc, NB (CYQM) to Fredericton, NB (CYFC) was given a speed restriction of 150 knots inbound until MITIK. After hand-off to the Halifax/Stanfield, NS (CYHZ) tower, C-FZKH slowed to below the speed restriction prior to MITIK. An I.M.P. Group Limited Cessna 560XLS (C-GSLC) from St. Johns, NL (CYYT) to Halifax/Stanfield, NS (CYHZ) was inbound to land at CYHZ and was overtaking C-FZKH. The controller attempted to maintain 3NM separation by slowing C-GSLC and by turning C-GSLC south to avoid C-FZKH. C-GSLC came within 1.6NM from C-FZKH before a turn was executed.

An Air Canada Airbus BD-500-1A11 (C-GNBE/ACA686) from Toronto/Lester B. Pearson, ON (CYYZ) to St. Johns, NL (CYYT) initiated a go-around due to deteriorating conditions and a new runway surface condition (RSC) report.

Aviation Incident Report #17435: A privately registered Mooney M20E from Sherbrooke, QC (CYSC) to Lachute, QC (CSE4) was on very short final Runway 28 when a 6800009 Canada Inc. Cessna 172N (C-GVWT) from Lachute, QC (CSE4) to Lachute, QC (CSE4), which was holding on Taxiway B for Runway 28, lined up and took off without any radio communication. The Mooney M20E had made prior radio announcements on the aerodrome traffic frequency (ATF) on downwind, base let, final and short final. The Mooney M20E had to conduct a go-around at around 200 feet above ground level (AGL) and lost sight of C-GVWT as both aircraft were almost vertical of each other. The Mooney M20E made a short low altitude left-hand uneventful circuit and came back to land Runway 28. C-GVWT continued on normal traffic pattern for Runway 28 and landed uneventfully 3 minutes later, without any radio communication made on the ATF.
