ACR IN HOLDING HAS TCASII RA REF SKYDIVE ACFT IN COM WITH ATC.

Narrative

DSNDED ENRTE INTO HOLDING AND LEVEL AT 14000 OVER BENKY WITH TCASII INDICATING OTHER ACFT AT 12000 AND 13000. ROLLED OUT ON OUTBOUND LEG; APPROX 1 MIN LATER; TCASII DEPICTED ANOTHER ACFT AT OUR 2 O'CLOCK ALSO AT 14000 FT. WE ASKED ATC TO CONFIRM OUR ASSIGNED ALT AND CURRENT ALT. HE REPLIED 14000 FT AND ALSO ADVISED OF VFR TFC. UPON TURNING INBOUND AGAIN; A CONFLICT AROSE WITH THE SAME ACFT Y; A TWIN; POSSIBLE TURBOPROP. TCASII GAVE AN RA AND WE TURNED AND DSNDED AND ANNOUNCED SAME TO ATC. OUR DSCNT WAS APPROX 1000 FT. UPON CLBING BACK UP AND SO ADVISING; ATC INDICATED WE COULD STAY AT 13000 FT. WE DISCONTINUED OUR CLB AT 13400 FT AND DSNDED TO 13000 FT. OTHER ACFT Y WAS INVOLVED IN PARACHUTE JUMPING AT OTTAWA ARPT. CONCERNS: ATC INDICATED HE WAS GIVING ADVISORIES TO Y; WAS AWARE OF HIS POS; AND IS UNDER A DIRECTIVE NOT TO REFUSE AN ALT TO JUMPERS; ONLY SUGGEST A HEIGHT AND RELEASE POINT. FAA PROTECTION OF HOLDING AIRSPACE. IF ATC IS NOT GOING TO CTL LOCATION OF VFR ACFT; THEY STILL HAVE THE RESPONSIBILITY OF CTLING IFR ACFT TO AVOID ANY CONFLICT. THIS WAS NOT DONE; RESULTING IN EVASIVE ACTION. CLOSEST POINT OF APCH APPROX 1 MI.
