Who we are

We are an association of

  • Civilians,
  • Law enforcement and EMS, and
  • Military personnel

that encourages the operational style of marksmanship training and competition, utilizing modern equipment and techniques.

We welcome all serving or former members of the military and law enforcement agencies as well as civilians of all ages. (See Membership page for complete details.)

Programs & Events

We offer training clinic, structured practices, and competitions for:

  • Duty/service pistol,

  • Tactical/service rifle, and

  • Sniper/precision rifle.

We provide both entry-level and advanced training clinics in these firearms. For each type of firearm, we have designed a progressive course of fire that will develop operational skills for those on active duty and develop marksmanship skills leading to national and international competition for recreational shooters.

See the Events page for details on this year's schedule, as well as further information about the courses of fire, clinic curricula, and match conditions.

OSA's official birthday is 07 April 2006 and our first event was a Pistol Clinic on 22 April 2006. Our first formal competition was the 3-Gun Match in September 2006... this is the OSA birthday cake enjoyed by the match participants.


OSA logo...

A special thanks goes to Craig McLeod, a "Friend of MilCun" for designing the OSA logo. Craig also designed the MilCun logo and carved the shield awarded to the World Individual F-Class Champion. Craig passed away in 2017 and is sorely missed.

OSA website...

A grateful thank you goes to Keith L, an OSA member, who built the shell for the OSA website and patiently tested and corrected through many content edits. Keith spent many hours on this project and we appreciate his dedication.

Thanks also to Rob L, an OSA member, who has converted our applications and renewals into pdf "fillable forms".

OSA ranges...

OSA uses the MilCun Training Center ranges, which are approved by the CFO (Chief Firearms Office) of Ontario. We are required to maintain the ranges at the pleasure of the CFO and this often costs a great deal of money. We appreciate all the support we get from OSA members and friends, because many of these requirements enable civilian use of the ranges.

OSA We also want to especially thank Founding/Sustaining member Carl B for bringing his wonderful heavy equipment and skill to upgrade the ranges.
