If you've done the math and you guys are going to save a bunch then by all means go for it. Just remember that just because you're within your legal rights doesn't mean the government is aware of it. Not all CBSA agents are fully aware of all importation laws. Guns and other items (airsoft and not) that are legal for import still get seized and sent for testing. This could mean you won't receive your gun for several months, this is a real possibility and however large or small you should be aware of and willing to accept the potential risk.

I personally like to support Canadian businesses whenever possible, if the difference is "small" I'd rather support my local airsoft store. It helps them grow keeps my money in Canada and doesn't promote excessive shipping distances etc etc end of lecture.

As far as a choice between the guns you've mentioned. I say go AK but I'm bias and don't care much for the G36. Both have a v3 mechbox but the AK has the advantage of a motor cage. The G36 probably has a better hop-up design, easier to adjust IMO. AK mags are taller but don't have the awkward tabs on them which make G36 mags more difficult to maneuver in and out of pouches. AK gear and accessories are more abundant. Other than that it's really up to personal preference of ergonomics and aesthetics.

CYMA AK's have a good reputation for being a great gun for the price and should last you a while. Not sure the difference between the different models but I'd go with the VFC style it's more realistic.

Sights are really a matter of preference. The G36 iorns are more spread out across the gun, one could argue that they're more accurate. But the AK sights are closer to the front making them better for quick acquisition.

Bottom line is that generally speaking although they're lighter plastic bodies are weaker then metal ones, especially in the cold when plastic can become brittle. Rarely does anyone ever break their gun on purpose but guns break. No one can tell you where, when or if you'll break your gun.
