C-GEJK proceeded to backtrack and turn onto Runway 36 at high speed. C-GEJK appeared to be starting a take-off roll and the tower instructed them to hold their position. Runway 36 was occupied by staff vehicles for painting, as well. C-GEJK was subsequently re-oriented for the correct runway.

A Harbour Air Ltd. de Havilland DHC-6-300 (C-GHHA/HR611) departed from Vancouver Harbour, BC (Water) (CYHC), northeast (NE) bound. At approx 500ft, the pilot announced they were returning immediately due to a high oil pressure indication. The aircraft landed safely. No operational impact.

From 1123Z until 1410Z the NAVNet/aeronautical fixed telecommunications network (AFTN) connection was disrupted at the London flight information centre (FIC). The FIC was unable to send or receive VFR and IFR flight plan data via the flight service station information management system (FIMS) to the appropriate Area Control Centres (ACCs) and FICs. Quebec and Edmonton FICs assisted with IFR flight plan entry. London FIC was unable to enter local weather observations via the Human Weather Observation System (HWOS) or provide weather observation contingency services to designated sites. Quebec FIC provided "buddy" weather services for London. Weather data such as the current meteorological report (METAR), the aerodrome special meteorological report (SPECI), and the Aerodrome Forecast (TAF) were not ingested or available on FIMS. NOTAMs could not be entered on the NOTAM Entry System (NES) on FIMS browsers. Specialists used Collaborative Flight Planning Services (CFPS) and NES on the NAV CANADA intranet (NCI) computers for weather data, pilot weather report (PIREP) entries, and to enter NOTAMs. External CFPS users encountered flight plan error messages and were directed to contact the FIC. There was a significant increase in workload as flight plan data was passed via phone and fax. The internal and external coordination, workload and complexity was high. East Coast air traffic service (ATS) units encountered delays or did not receive electronic strip data for VFR flight plans. When AFTN connection was restored, there were numerous queued and duplicate flight plan data messages that needed to be examined and triaged. The outage was traced to a Zayo telecommunications (Telco) company circuit. Backup routers did not engage.

The pilot of an American, corporately registered Diamond DA 42 (N591ER/DIM18) from London, ON (CYXU) to London, ON (CYXU) departed from Runway 09 and immediately reported a problem with the aircraft.

No fire or injuries reported.

An Air Canada Airbus A321-211 (C-FGKZ/ACA144) from Calgary, AB (CYYC) to Toronto/Lester B. Pearson, ON (CYYZ) initiated a missed approach to Runway 05 due to being too high on the approach. ACA144 landed on Runway 05 at 0009Z without further incident (WOFI). No impact to operations.

A privately registered Mooney M20C from Muskoka, ON (CYQA) to London, ON (CYXU), returning from CYQA, did not have a functioning transponder.

The aircraft landed safely once traffic levels permitted.

A WestJet Boeing 787-9 (C-GUDO/WJA4) from Gatwick, United Kingdom (EGKK) to Toronto/Lester B. Pearson, ON (CYYZ) was instructed to initiate a missed approach to Runway 23 due to an Air Canada Airbus A320-214 (C-GJCT/ACA262) from Winnipeg/James Armstrong Richardson, MB (CYWG) to Toronto/Lester B. Pearson, ON (CYYZ) missing high speed exit H2 after landing on Runway 23 and being slow to exit. WJA4 landed on Runway 23 at 2132Z without further incident (WOFI). No impact to operations.

The Montreal Area Control Centre (CZU) handed off an Alaska Airlines Boeing 737-900 (ASA840) from Boston, MA (KBOS) to Seattle-Tacoma, WA (KSEA) to the East High/Picton controller and advised the aircraft was "no radio" (NORDO). The aircraft transited Toronto Centre (CZY) airspace at FL320. Communication was established at 1620Z. The North American Aerospace Defence Command (NORAD) was advised. No operational impact.

After receiving area navigation (RNAV) 07 approach clearance from the terminal radar approach control (TRACON), a Jazz Bombardier CL-600-2B19 (JZA8359) from Toronto/Lester B. Pearson, ON (CYYZ) to Windsor, ON (CYQG) requested to overfly Runway 07 due to being too fast and high after maneuvering to avoid VFR traffic in the vicinity of IPTOD (the initial fix). The CYQG controller took control of JZA8359 and cleared them for a left-hand circuit after overflying the runway. JZA8359 landed safely at 1925Z. A Windsor Flying Club Cessna 172R (C-GAVV) from Windsor, ON (CYQG) to Windsor, ON (CYQG) who was working outside the control zone was given a suggested heading and altitude to remain clear of JZA359s path.

An Air Transat Airbus A321-211 (TSC947) from Fort Lauderdale, FL (KFLL) to Toronto/Lester B. Pearson, ON (CYYZ) advised they were too high on the approach, and required an overshoot.

While on approach for Runway 23, the tower controller instructed a WestJet Boeing 737 MAX 8 (WJA2509) from Punta Cana, Dominican Republic (MDPC) to Toronto/Lester B. Pearson, ON (CYYZ) to conduct a go-around due to a United Airlines Airbus A320 (UAL2233) from Houston, TX (KIAH) to Toronto/Lester B. Pearson, ON (CYYZ) that was still on the runway. UAL2233 had missed both high-speed exits.

A 2080061 Ontario Inc. (C-GCPX) from Sioux Lookout, ON (CYXL) to Kenora, ON (CYQK) was cleared for a specific approach at Kenora and was switched over to YQK flight service station (FSS). 3 minutes later, YQK FSS reported the pilot executing a 360 degree turn because they were too high on the approach without authorization. No other aircraft in the vicinity. No impact to operations.

An inbound Aviation Starlink Dassault Falcon 2000EX (C-GROG) from Chicago/Midway, IL (KMDW) to Toronto/Lester B. Pearson, ON (CYYZ) was instructed to level off at 8000 feet, and a WestJet Boeing 737-700 (WJA535) from Toronto/Lester B. Pearson, ON (CYYZ) to Winnipeg/James Armstrong Richardson, MB (CYWG) that was departing from CYYZ was instructed to climb to 7000 feet. Traffic was pointed out to both aircraft and they had each other visually. The high climb rate of WJA535 triggered the resolution advisory (RA) on both aircraft. C-GROG climbed to 8200 feet. No operational impact.

A Bearskin Airlines Swearingen SA227-AC (C-GMEW/BLS7010) from Sudbury, ON (CYSB) to Thunder Bay, ON (CYQT) rejected its take-off roll. The aircraft tried a high speed taxi on the runway shortly after, then cancelled its flight plan after taxiing back to the apron. No reason was given. No impact on operations.
