No, that's not the case at all. There is no declaration to permit airsoft guns into the country, they can only be imported by a business with the appropriate license.
That thread is relating to air travel inside Canada, where there is no customs issues - it has nothing to do with international travel. Bringing airsoft in your luggage from overseas will have it seized and land yourself in a shitstorm at the airport. Don't even thinking about it.
