Canadian Vis minima
Please excuse my ignorance...
Im looking at some Jepp canadian approach plates, and am struggling to understand the visibility minima.
For example, CYHZ ILS RWY 23 CAT I, with the full lighting system available it says RVR26 OR 1/2.
My thinking, and please please, correct me if Im wrong is that its 1/2 statute mile? But im stumped by the RVR units?
Finally there are JAA minimums pages, where for the same approach mentioned above, its lists the vis minima as R26 V1/2.
Any help would be greatly appreciated
Many thanks

The visibilities printed on the approach plates in the CAP are advisory only. They constitute a minimum for a "high probability for a successful approach" if I remember the wording correctly. As the Canuck said, approach ban is 0.25 mile or RVR 1200. If there is an A & B(mid point) RVR, then the B can be RVR 600.

And of course all of the above changes tomorrow...December 1st.
Check the CAPS or your company Ops Spec...Charted vis is no longer advisory.
Life just became a little bit more complicated!!
