Just to flesh out the above discussion…….
Largest Arenas in Canada (Wikipedia)
#1 Bell Centre (Montreal) - 21,273
#2 Saddledome (Calgary) - 19,289
#3 Canadian Tire Centre (Ottawa) - 19,153
#4 Air Canada Centre (Toronto) - 18,819
#5 Rogers Arena (Vancouver) - 18,810
#6 Copps Coliseum (Hamilton) - 17,383
#7 Rexall Place (Edmonton) - 16,839
#8 Pacific Coliseum (Vancouver) - 16,281
#9 Credit Union Centre (Saskatoon) - 15,195
#10 Colisee Pepsi (Quebec City) - 15,127
#11 MTS Centre (Winnipeg) - 15,005
#12 Metro Centre (Halifax) - 10,595
#13 Civic Centre (Ottawa) - 9,862
#14 Budweiser Gardens (London) - 9,100
#15 Memorial Auditorium (Kitchener) - 7,268
#16 Save-on-Foods Centre (Victoria) - 7,006
#17 Moncton Coliseum (Moncton) - 6,554
#18 WFCU Centre (Windsor) - 6,500
#19 Mile One Centre (St. John's) - 6,247
#20 Harbour Station (Saint John) - 6,200
So, as it is, Moncton currently has the 17th largest arena in Canada. If a new 7,500 seat downtown events centre gets built, then we would move up on the list to number 15. If we went for a 10,000 seat arena, we would move up to #13.
I still think 7,500 seats is too small for major events. A bare minimum as far as I'm concerned is 9,000. I would still prefer 10,000. We would then be in the big leagues as far as a performance venue is concerned. I think you break a certain psychological threshold if a venue can seat 10,000 or more.
