There are a wide range of opinions on what sling works best, but after I've tried three points, single points, I ultimately settled on a traditional two point - well a hybrid sling that gives me the ease to transition from a one point to two point or vice-versa. It took me awhile to find the optimal sling for my AR, I went from a three-point sling, which was a nightmare if you had to switch from your dominate hand to support hand to shoot or the third strap always seem to get in the way while performing a reload, then to a one point because of those problems. But after running with a one point on my AR15, even at the range, which one is pretty much static, the weapon retention was lacking horribly, even though it was great as a shooting sling, easily manipulate the controls of the weapon, shooting ambidextrously with ease, but I found my muzzle would swing around horribly, especially during weapon transitions drills. It was difficult to perform any simple tasks requiring two hands, let alone if someone had to put their hands on a subject, climb a ladder, rope, or do any of that ninja tacticool high speed stuff, without one hand keeping the muzzle still. I tried using Blackhawk's CQD Mark II Weapons Catch, which did the job, but I found it cumbersome and slow to secure the weapon for a weapons transitions or to perform other tasks, not to mention you always would have to have it part of your kit. After getting fed up with it, I finnally went and got a traditional two point.Two commercially available two points on the market for the AR that are highly recommended are Kyle E. Lamb's V-TAC sling or Blue Force Vickers Combat Application Sling. After T&Eing both, the V-Tac is my favorite, even though the VCAS edges over the V-Tac in quality of construction, stitching and overall feel - (also someone mentioned it has a lower IR signature, can't confirm, but I could care less about, just remember reading it somewhere or another), for me the length adjustment is not as easily with the VCAS, can't continually make the sling taut - pulling it closer to your body as you can with a V-Tac. The generation one V-Tac slings had a free running tail which I've comically had go into the mag well during a speed reload, but this is resolved with the gen 2s, Mk2, with an additional velcro nylon assembly that keeps it in the free tail in line with the sling. I also tried the Magpul MS2 sling, which I especially like the quick detach hardware, and the concept of two slings in one, easily go from a one point to two point sling or vice-versa. However, just like the VCAS, the MS2 length of adjustment or the ability to continually make the sling taut was missing feature. So what I ended up doing was making my own hybrid sling, took a V-Tac Mk2 Sling, the hardware from the Magpul MS2 sling. So far, it's running pretty well, and with the hardware, the nice thing is the sling can stay on me, and I can also mount the sling on different guns, like my 870 or any other gun easily - assuming they have the corresponding correct hardware mounted. This is by far the best sling I've used thus far. It utilizes a two point sling setup, which is designed for muzzle down carrying. One can adjust the length of the sling in seconds, allowing the user to perform various tasks quickly, this is accomplished through the use of a free running tail or the quick release lanyard, and when expecting to shoot, the sling can easily be transition with the claw to a one point, giving the flexibility to shoot easily off the left or right shoulders without the straps choking me. The design of the V-Tac sling is simple, tried, true, and tested in combat, combined with the innovation from Magpul theory products, the MS2 hardware, snap hoop and claw, makes for the sling I've used thus far that seems to provide the best of both worlds.

Hopefully sharing my experiences will save you some time and money. The last few pictures is the latest iteration of what I am running so far on my AR, I don't have any complaints, well now that I think about it, it can be a little difficult to hook the front end while transitioning from a single point to two point sling, probably best to use a fixed loop opposed to the QD sling swivel on the rail, since by design it can swivel. And if you do go for a V-Tac or VCAS, be sure to spend the extra and get the padded version, definitely makes a world of difference when your out there for long periods of time. Well, that is if your running slick, no 2nd line gear, if you do run a big vest 2nd line or even 3rd line, you can save the $10 and just get the standard, there's no difference on the load carrying ability, but comfort wise, makes a huge difference if your just out there with a 1st line rig.
So here's a shameless plug for Kyle, which developed the VTAC sling:
Sergeant Major Kyle E. Lamb (retired), spent more than 21 years with the United States Army, more than 15 years of which were with the U.S. Army Special Operations. SGM Lamb has conducted combat operations in numerous theatres of operation, including Mogadishu, Somalia (Black Hawk Down Incident), and has served numerous tours in Iraq (the current war as well as Operation Desert Storm) and Bosnia. SGM Lamb is now the Founder and President of Viking Tactics, Inc. as well as the author of “Green Eyes and Black Rifles: The Warriors Guide to the Combat Carbine.” Lamb is a highly sought after military and law enforcement trainer, conducting Leadership Training Seminars, Team Leader Planning Courses, Tactical Commanders Course, Active Shooter Courses, Dynamic Tactical Entry Courses, as well as Carbine and Pistol Courses.

Don't know if he ships to Canada though, don't believe it's ITAR controlled.
Oh and I forgot to mention the hardware, on your gun. If you run a basic VTAC sling, you'll need at least a sling swivel on the rail or front of the gun, with a standard M4 telescopic stock you can loop the ends together, and it works to secure the buttstock end, just no quick detach feature. (See the first picture with the ICS M4 on the right hand side.) I prefer the QD, since I can keep the sling on my body in a one point set up. But it's up to you, if you want to keep a sling always on the gun, or would rather have QD. Mounting a two point far from end to end, will allow the weapon to clench onto you better, but makes it more difficult to shoot off the support side, ambi shooting is easier when it's mounted on the end plate/castle nut between the lower receiver and buffer tube, also seems to hang just right in a single point from the end plate rather than stock. So I'd recommend mounting it on the end plate and to the forend for two point, and on one point directly to the end plate. And since this is for airsoft, you might want to check your barrel nut is properly torqued and secured, and that your receiver had handle the weight of your weapon, before you go lugging it around like the real thing. Depending on where you mount it, it can cause enough torque as to work your barrel nut loose, or work your free float or even non free float rail loose, or put a lot of stress and strain on your barrel, if you mount to the front sight base, since airsoft outer barrels aren't exactly cold hammer forged steel.
(Note: If you get a MS2 sling, get the PTS one, the real one doesn't have a swivel joint on the snap hook, not sure why not, but that swivel joint on the snap hook that goes to the rear end, prevents the sling from binding up, as it can with the real MS2 or MS3 sling, there is a swivel joint allowing rotation along the axis of the strap, but only on the claw hook not the snap hook).
