i know this thread is sorta old (Oct 2010), but i should point out that NCRRA / Connaught is NOT available to you if you're not a member, since your regular-club ATT will NOT permit you to take it to a FEDERAL range. you can take it to other clubs if you already have an ATT (unless the club itself says no), but as far as Connaught is concerned the CFO is the one saying "nope, sorry".
this is why if you're in ottawa, you should get our ATT via membership at Connaught, since then that lets you take your gear anywhere - Federal and Private ranges. an ATT from a private range is for private only. plus you can shoot your AR-15 at the 100-900m rifle ranges as well as on the 25m pistol range (but NOT on the 50m pistol range). so you can do some short-distance stuff too - as close as 5m if you so desire.
