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.

Equipment

OSA focuses on three types of firearms:

• Pistol,
• Hunting rifle, and
• Long rifle.

We look forward to the day when we can once again include service/tactical 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

2026 Winter Events - January to March

OSA Snowshoe & Shoots haven't been conducted for the past year or two, but if we start them up again... 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. The winter events were suspended for 2025. We'll let you know if they resume.

2026 Spring Events - April to June

OSA Spring Events focus on clinics, and usually include the Pistol Clinic, Holster Course, and any other qualification clinics.

The Junior Hunter Program is an important part of the schedule. It's for Juniors and their mentors, with the 3 training days ending with a competition on National Range Day on the first Saturday in June.

OSA is adding a new event, OSA Service Rifle. The matches are an echo of the NSCC/DCRA matches, but with some changes that make it more fun (and less training intensive) than the original. The OSA folks who are knowledgable in this type of event have been working with Keith to iron out the details. A description will be included in the PractiScore listing and we'll post the draft Course of Fire as soon as we've settle on this year's trials.

We liked the "One and Done" trial we did in 2025, so we're offering it twice in 2026. It's an event to test your long-range accuracy and knowledge of your equipment.

We'll continue to offer M-Class, 22 M-Class, MOS, and Running Boar. This year we're trying to have one of each of these every month. Just a note on the MOS... that's MilCun Operational Sniper. It's very similar to the DCRA/NSCC Precision/Sniper event... shot in shooter/spotter pairs with double-tap snaps and movers and deliberate fire.

Last year's Historical Military Rifle was not well attended, so we've decided to invite these shooters to our other events (like service rifle) and if enough show up, we'll give them a class of their own. 22LR Field Hunt has been well-received, so we'll have at least a couple of these events. The OSA First Aid course for MilCun range was well received, so we'll plan to offer this every other year.

Richard M from our affiliate club in Ajax will be running a shotgun scenario clinic at the end of June, a pistol scenario practice at the end of August, and an any rifle scenario day at the end of September.

MilCun is offering an Advanced Police Pistol and Carbine MARKSMANSHIP course in May, plus a Police Pistol and Carbine INSTRUCTOR course in June.

2026 Summer Events - July-August

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 Course. This year, MilCun will also be offering an Advanced Wind Reading course in August.

The OSA Summer Events continue to include the usual M-Class, 22 M-Class, Service Rifle, MOS, and Running Boar.

We invite the military/historical rifle afficionados to come out to any of our other events.

And we've scheduled 22 Field practices and a 3-gun IDPA-style scenario day.

If we get our rights back, we will start up the clinics and practices that use the firearms we put in our closets back in the spring of 2020.

2025 Autumn Events - September- October

In late August, MilCun offers the Hunter Marksmanship Weekend course and OSA offers a 1-day match, The Hunters Challenge.

Autumn brings us to the championships for several disciplines: MOS, M-Class, 22LR M-Class, Operational Pistol, and Running Boar.

Tactical Rifle Match Descriptions

With the federal government Order in Council published on 01 May 2020, our tactical rifle matches are suspended at this time.  

Service Rifle Match Descriptions

We've decided to pursue a NEW service rifle course of fire, suitable for rifles that are still legal in Canada. A special interest group has been working with us all winter to develop the rules and match descriptions. They are still in DRAFT form, and there will likely be changes as we work through the practices.
