2024 MilCun and OSA Calendar will be built over the next few months. We'll keep you posted as we confirm our many events.


If you're new to OSA, make sure you email us for a copy of the OSA event Joining Instructions before you come. 

All participants at OSA events must have "liability insurance for all shooting activities" which is a benefit of membership in organizations such as the CSSA, CCFR, and NFA.



OSA focuses on three types of firearms:

  • Pistol (duty, service, operational),
  • Service rifle, and
  • OSA Operational-style precision/sniper rifle.

For practices and clinics, the participants may use any equipment that they would like that's legal for the range. For competitions, in general terms, the equipment is required to be operationally oriented, either the kind of thing that is currently used by military or law enforcement, or that could reasonably be used by them. Anyone who wants to shoot a match with other equipment is welcome to shoot for honors only.

OSA Events - Descriptions

2023 Winter Events - January to March

OSA Snowshoe & Shoots - We meet at the driveway parking area at the MilCun Training Center and snowshoe in to the ranges. You must be fit enough and properly dressed to enjoy about 7 kms of cross-country snowshoeing. You will need to carry your firearm and ammo, as well as all personal kit (such as lunch and water) for the day.

2023 Spring Events - April to June

OSA Spring Events focus on clinics, and usually include the Pistol Clinic, Holster Course, and any other qualification clinics, as well as M-Class Practices, Service Rifle Practices, Pistol Practices, OSA "MOS" Rifle Practices.

MilCun Training Center is very busy in the spring with police courses and police agency custom courses and range rentals, so our civilian courses usually get started in July with the MilCun Enhanced Rifle Courses.

2023 Summer Events - July-August

OSA Summer Events usually include more practices and some matches. More details as we get our schedule fleshed out.

Please note that OSA is no longer going to provide training specifically for the NSCC matches. We'll continue to hold the OSA Operational Pistol events (on which the NSCC pistol matches are based) but we will not adopt any of their new changes. Similarly, we will not be following NSCC service rifle changes, instead we have remodeled our program to suit bolt-action service rifles. (Semi-automatic service rifles that are restricted or non-restricted are welcome to join in.) We will no longer be following the NSCC Precision/Sniper matches, instead we'll offer Operational Sniper Matches of our own and OSA Operational M-Class (an operational-style F-Class).

A favorite OSA event, the Canadian 3-Gun Championship (C3GC) has been rebuilt as the Canadian 2-Gun Championship (C2GC) so that our off-duty and retired members can bring personal equipment to the match. We have been supporting the various challenges to the OIC, and we sincerely hope we'll be able to reconstitute the 3-Gun soon. This event is open to police, military, armed security, and emergency services personnel.

MilCun Training Center is planning to run the Enhanced (Long-Range) Rifle Skills course in July or August.

OSA CoF - 2022 Service Rifle - 2022-02-22

With the federal government Order in Council published on 01 May 2020, our service rifle matches have been changed. Many AR-style rifles are now prohibited, so we will be modifying the matches to enable the use of bolt-action and other styles of rifles. Match trials and tests were held during 2020. The matches and rules were reviewed by our working group. We've scheduled several Service Rifle practices and a Championship in 2022. These events will be governed by the new rules.
