2019 OSA Events - Schedule (19 May 2019 version)

Includes Eventbrite links through to the end of of 2019.

We continue to use the EventBrite online registration system for OSA events. The events are listed as "private" on Eventbrite, so you can't search for them. The links are published through our OSA Update emails and they are listed on the Schedule.

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

For MilCun courses and other events, email the registrar (as noted on the Schedule).

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



OSA focuses on three types of firearms:

  • Pistol (duty, service, operational),
  • Tactical/service rifle/carbine, and
  • Sniper/precision 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.

At the request of our members who are planning to compete at NSCC, we've moved our Service Rifle Championship to mid-August. And the Precision/Sniper match is also in August, ahead of NSCC.

A favorite OSA event, the Canadian 3-Gun Championship (C3GC) is normally scheduled for the first Wednesday after the Ontario Civic holiday. This is open to police, military, armed security, and emergency services personnel. Prior to this event, we may hold an open 3-Gun Challenge for civilians as well as those who qualify to shoot the C3GC.

The NSCC matches (pistol, service rifle and sniper/precision rifle) are currently in the plans for 2019... but confirm the dates with the DCRA before you make your plans because we no longer control that schedule. You can enter any or all events. For details, watch the DCRA website www.dcra.ca.

MilCun Training Center is may be running our Enhanced Pistol Skills course this summer as well as one of our most popular courses... the Enhanced (Long-Range) Rifle Skills course. We've also been asked to include PRS-style training and matches, but we may run out of weekends before we get everything in place.In August, we usually run the Precision/Sniper Competition course, which develops your skills for the NSCC/ORA Precision/Sniper matches. For details, www.milcun.com.

Women's Day is moving on to its 11th year and we'll try to give it a prime date for good weather.

The Argyll Cup (usually the first Thursday after Thanksgiving) has become one of the most respected challenges in the police/military sniper world and it is our OSA volunteers (and the "friends of OSA" volunteers) who make it what it is. Once you've been here, you'll know we really mean it when we say, "We can only do it because of you."
