Club rules are just that, club rules. Most clubs will follow a general rule book from some sanctioning body but will alter a few of the rules to not discriminate from those who do not have rifles that fall into a class. They do not want to discriminate against those so they alter the rules to get more shooters. This is great for the club.
BUT
When it comes to make something more formal like a registered match, which I would love to see for Centerfire score or Rimfire score, it becomes almost impossible. Clubs do not want to loose shooters to formalizing any sort of match. Look at Rimfire and the different targets and scoring clubs use just reading these posts?
Honestly, I have never shot Dwayne's rimfire match but I will. If not this year next year for sure. To many irons in the fire in the BR world. Still have Centerfire things to pay for this year.
I like the format they have using the IBS target. It is not about using a target that is tough, yes there are tough Rimfire score targets out there, and worst edge scoring. It is about encouraging the shooter that may not have the funds to go full blown. In my opinion some targets are rather discouraging to shoot. JMO.
Getting back to your original question I doubt there are any Rimfire matches in Canada that follow any rule book to a tea. Again JMO
