Called Garage Doors of Ottawa at 10AM and they were able to get some one out to replace 2 broken springs and cables by 4PM same day for an excellent price of $250 + tax. The installer came exactly when they said they would come and finished the job within about 15 minutes.
I had also called another local supplier and they had quoted $423 but weren't able to send some one until the next day just to measure the springs. Then they would come back a second time to complete the work. The other supplier price was out to lunch compared to what it cost for material and the labour involved which is very short.
I highly recommend Garage Doors of Ottawa.
