At approximately 100 nm SE of CYWG, FDX134 requested a descent from flight level 380 and was cleared to flight level 290 by Winnipeg Centre Area Control Centre (ACC). FDX134 subsequently started the descent. ACC then cleared B-2094, a Boeing 777-FFT operated by Air China Cargo as flight CAO1054 at flight 330, to turn right 10 degrees to provide separation with FDX134. As FDX134 was descending through flight level 340, the crew of FDX134 asked ACC about traffic ahead of them. During the radio transmission regarding the traffic, FDX134 received a TCAS TA/RA to climb. FDX134 complied with the TA/RA, notified ACC of the manoeuvre and advised once clear from the traffic. FDX134 continued for an uneventful landing at CYWG. Review of the available radar information indicates that the nearest distance between the two aircraft was 5.1 miles laterally and 600 feet vertically. Minimum separation requirements are 5 miles or 1000 feet.
