I'd argue that your statement seems uneducated... There are dozens of fantastic Ottawa bands... Many of them don't get talked of much on here, everyone is too busy talking about BNB or nero...
Relief Maps, the Soiree, Jetplanes of Abraham, Acres, M$M, Department of Foreign Affairs, the Acorn, Double Pumpers, Ukrainia, Reverb Syndicate, Hilotrons, Soft Disaster, Empiricals, Weapons of Mass Seduction, Black Boot Trio, Fiftymen, Golden Famile, Poorfolk, My Dad vs Yours, Crush Buildings, many many more plus all the punk and hardcore bands.
Ottawa has an awesome scene, IMO. I can go see good bands most nights of every week. (Although it gets difficult in the fall / winter due to hibernation)
