GBS = General Bearing Service
They are a bearing and industrial supplier in Ottawa (with other Ontario and Quebec branches). Unfortunately for you, their nearest branch to you is in Whitby.

Another supplier Bob and I use is Industrial Solutions, also Ottawa and Quebec based

Hamilton is more industrial than Ottawa so there have to be suitable suppliers down there. Maybe:

One of the things we like about the 2 Ottawa locations mentioned is that each of them have at least one staff member who has a very good memory for older bearings and a genuine will to solve challenges locating odd bearings for clients. As an example, a couple of years ago GBS was able to locate a (small) supply of the 928 bearings used in 4x4 CMP steering joints. The bearings were in Texas and they were willing to get them in virtually overnight. Unfortunately, the price was beyond what I was willing to pay for bearings to have on hand in case of a future need.
