Twice I've looked for one of these in Canada and twice had to order it directly from Lyman.. they will ship to Canada but they're not super fast.
Forget the case gauges and get the Hornady cartridge case headspace gauge, and you will only need to buy "ONE" gauge for all calibers.
The Wilson case gauges in the rear have been retired, all I use now is the Hornady gauge.
You can adjust the gauge to read actual headspace.
Colt Field gauge for a AR15 rifle, 1.4736

Below, my retired Wilson 30-06 case gauge that I now use as a paper weight and pen holder. (hint hint)

Wait.. I have one of those Hornady case guages. I thought I could only use them for determining how much to bump back the shoulder for ideal fit into my chamber. Are you telling me the Lyman go/no-go gauge I have for .223 and the one I just ordered for .308 are useless?
A Wilson or other of the same type case gauges just measure from the shoulder to the base of the case, these type gauges have steps cut into the top for min and max case length. These type gauges do not check body diameter and only measure cartridge headspace length, the Hornady gauge measures the same dimensions but will give you a dial or digital reading. I'm not telling you the Lyman gauge is worthless, BUT when you have chronologically gifted eyesight the dial or digital reading is easier to "SEE" and a more accurate gauge.
On top of this if you adjust/calibrate the Hornady gauge it is no longer a comparator gauge and reads actual headspace.
Below a fired Federal M193 case that was fired in my AR15 rifle.
Below the same case resized with .003 shoulder bump.
Below, new unfired M193 ammunition headspace .002 shorter than a GO Gauge.
If you want a gauge that measures case diameter you need a gauge made from a chamber reamer.
JP Enterprises Case Gauge manufactured from actual match chamber finish reamer. JP Enterprises Case Gauge checks head space and case diameter. It is the only case gauge that checks minimum and maximum for headspace, case length and case diameter.

IMO, the Hornady one measures spent cases whereas a go-nogo gauge allows one to set the headspace before shooting.
It's like "hey, this case didn't blow in my face, let's have it measured with the Hornady gizmo".

Right.. Thanks for the tip. I guess I didn't think it through.
The only thing I think the Lyman or Wilson gauge might do that the Hornady doesn't is show when the neck is too long. For that I use calipers anyway, since it's way easier than looking at the little machined surfaces on the metal gauge.
Thanks for the tip.
