Boy, I hate to do this to my American cousins, but there are no visible shortages up here in Canada. I just came back from the Toronto Bass Pro Shop and the small Hamilton gun shop I go to. All shelves are stocked, including reloading sections. That includes .40, 9 mm, and all rifle calibres. No issues with shotshells, either, you can still pick up 150 double-ought buckshot shells for $120.00.
At my local ship I bought two 500-round bricks of .22LR ($22.00 each), and 250 rounds of surplus 7.62X39 for $0.28/round. We can also still get 1600 rounds of .223 for $499.00 by mail order within Canada.
I haven't seen any price increase, shortages, or heavier-than-usual buying.
