I recently bought a SRU Scar L from a retailer in Hong Kong. It arrived in a week with no problem except it had the CBSA's tap on it, meaning it was inspected.
The risk is minimal for ordering from Hong Kong as they are pretty good at preparing all the necessary documents. And the cost, with all the exchange rate and custom duties, is reasonable.
Krytac is a brand from US, so it may be different.
On a second note, I found the Canadian airsoft market has gradually going back to the "dark age" i.e. unreasonably high prices, lack of most updated/exciting gun models (a lot of M4 variants). Luckily a very few retailers still offer some good deals/updated models (which are sold out fast).
