There were no calls for the next 10 minutes until the Cessna 340A reported inbound on the area navigation (RNAV) Z approach. The tower passed traffic information to the Cessna 340A from an inbound aircraft on an unassigned code. Traffic information was passed 3 times before the Cessna T337G reported turning final for Runway 16, 3NM in front of the Cessna 340A. The Cessna T337G was given a left turn back, northbound, to follow the Cessna 340A. No other impact on operations.

At Terrace, BC (CYXT), a vehicle (EFCTK1) requested access onto Taxiway A. Flight Services gave EFCTK1 permission onto Taxiway A.

A Coldstream Helicopters Ltd. Bell 407 (C-GVIH) was completing work for BC Hydro near Invermere, BC (CAA8), with a pilot and 2 passengers (PAX) on board. Upon return to CAA8 at the end of the workday, the pilot observed a remotely piloted aircraft system (RPAS) operating 50 meters from the helicopter. The RPAS was described as a large one, with a width of approximately 16 inches by 18 inches. The pilot landed the helicopter without further issues, but they confronted the RPAS operator upon landing, who was standing near the helipad. The pilot was unclear why the RPAS operator was flying the RPAS at the airport, but the pilot believes that the RPAS operator was attempting to film landing and departing aircraft. The RPAS operator did not have a radio capable of ground to air communications and was therefore unaware of aircraft operating in the area. The RPAS operator claimed to be a licensed operator, and they gave the helicopter pilot their contact information. The 2 BC Hydro employees in the back have filed reports with BC Hydro (their employer), as all 3 persons onboard the helicopter were "rattled" by the occurrence. A Transportation Safety Board of Canada (TSB) investigator discussed the situation with the "defacto" airport operator, and the airport operator was not informed of any RPAS activity happening at the airport that day.
UPDATE: Aviation Incident Report #16995: The operator of a DJI Inspire 2 drone was operating at Invermere, BC (CAA8). The operator was flying the drone approximately 5 to 8 meters above ground level (AGL) while filming the pilot of a Cessna 177 and 2 passengers pushing the aircraft. The operator was in direct communications with the pilot of the Cessna 177 as they were only 20 meters apart. The drone had just commenced when a Coldstream Helicopters Ltd. Bell 407 (C-GVIH) on a flight to Invermere, BC (CAA8) arrived on short final. The drone operator did not have communication with C-GVIH. The drone operator brought their drone back toward the take-off area, which was just beside the hangar, while always maintaining sight with C-GVIH and keeping the drone at a low level. C-GVIH landed without incident and shut down. The drone operator moved the drone further from the hangar area, but continued to hover at a low level. The drone operator landed shortly after C-GVIHs flight operations had ended. C-GVIH and the drone operator communicated about the failure in communications and radio protocol.

An Insignia College Ltd. Cessna 172K (C-GDON) from Vancouver/Boundary Bay, BC (CZBB) to Vancouver/Boundary Bay, BC (CZBB) departed from Runway 07 and declared "MAYDAY" due to "control issues" through 400 feet. The aircraft was given the option to land on any runway. C-GDON landed on Runway 25 without issue and exited via Taxiway G. The aircraft advised the ground controller that it had experienced a "flaps issue".
UPDATE: TSB Report #A21P0017: C-GDON, a Cessna 172K aircraft operated by Insignia College, was on the first take-off for circuits at Vancouver/Boundary Bay, BC (CZBB) with one student pilot on board. The student took off from Runway 07 and, during the climb, realized the aircraft airspeed was decreasing. As the aircraft was nearing a stall at 300 feet AGL, the pilot regained control by lowering the nose to keep the speed up. The pilot declared a "MAYDAY" and ATC gave the pilot the option of "any runway". Other traffic was cleared to allow C-GDON runway access. The pilot managed to make a 180 degree turn to land on Runway 25 without further issues. After landing, the pilot realized they had set "full flaps" and did not set them for take-off prior to departure, as required in the pre-flight checklist. Ground taxi clearances were obtained and the aircraft taxied back to the company facility.

An Air Transat Airbus A321-271NX (TSC862) from Toronto/Lester B. Pearson, ON (CYYZ) to Calgary, AB (CYYC) was instructed to taxi to Runway 06R via Alpha and Delta, cross Runway 33R and Runway 06L, and hold short of Runway 06R, which was read back correctly. After crossing Runway 06L, TSC862 entered Taxiway D6 vice D. The controller advised TSC862 of the error and gave them the distance remaining. TSC862 advised they were okay and were cleared for take-off (T/O) from D6. No operational impact.

A VFR target was observed entering the Sudbury, ON (CYSB) control zone on the approach path for Runway 04. Contact was confirmed visually as a float plane at circuit altitude. The aircraft squawked its identification when queried but did not respond on the frequency. The aircraft subsequently exited the control zone (CZ) over Whitson Lake, then re-entered the CZ south of Hanmer. The aircraft, a 1789666 Ontario Ltd. Cessna 175 (C-FGAK), gave its aircraft identification (ACID) at this time and exited the CZ, remaining clear until established northeast (NE) bound.

Pearson Intl, ON (CYYZ). During cruise at FL350 in the vicinity of Elizabeth City Coast Guard Air Station, NC (KECG), ATC gave the flight crew clearance to proceed direct to the OPHEA intersection. After the flight crew turned direct to OPHEA, ATC then instructed them to turn to the right of track heading 210. Shortly after, ATC instructed the flight crew to descend to FL340. The flight crew began the descent, then ATC instructed them to expedite the descent to FL340. During the descent, the flight crew received a TCAS RA (resolution advisory).

A Perimeter Aviation de Havilland DHC-8-102 (C-GWPS) from Thompson, MB (CYTH) to Thompson, MB (CYTH) made initial contact with the specialist while on Taxiway Alpha, looking to cross the runway for Apron 2. A Keewatin Air Beech B200 (KEW208) on a MEDEVAC flight from Thompson, MB (CYTH) to Baker Lake, NU (CYBK) was taxiing on Charlie for Runway 24 at the time. C-GWPS gave way and taxied behind the backtracking traffic.

An American, corporately registered Gulfstream IV (N77WL) from Washington/Dulles, VA (KIAD) to Edmonton, AB (CYEG) lost communications with the arrival controller. They did not check in with the tower, and were given the green light and a landing clearance, but gave no response. Once landed, they called ground control on Taxiway Bravo.

Aviation Incident Report #17060: Customer Service Agents (CSA) contacted Operations to advise that a passenger on a WestJet Encore Bombardier DHC-8-402 (C-GWEN) from Calgary, AB (CYYC) to Fort McMurray, AB (CYMM) was issued yellow and red cards for non-mask compliance. CSA requested Operations assistance on arrival. The crew also gave a statement to the CSA on arrival. The passenger was non-compliant for the entirety of the flight and was issued a yellow card while the aircraft was circling CYMM. The aircraft eventually diverted to CYYC due to poor weather, and that is when the Flight Attendants issued a red card to the passenger. Upon landing at CYYC, police took the passenger into custody.
