Narrative:

Research done about canadian airspace did not catch that an IFR or controlled VFR clearance is required to fly between 12;500 feet and 18;000 feet. To check the pressurization system we climbed to around 16;000 feet and then descended for an approach into [destination airport]. When we contacted tower they informed us that moncton approach was attempting to contact us. We contacted them and they asked if we knew we needed a clearance to fly above 12;500 feet. I told them that our research of canadian airspace did not reveal that. I asked them if they wanted me to call them when we landed and the answer was they would have [tower] give us the number if they wanted us to call. We didn't receive any phone numbers.future flight in canadian airspace will have more diligent review of the airspace rules and all flights will be conducted with some form of flight following.

Title: BAe 146 flight crew reported they improperly operated in Canadian airspace between 12;500 feet and 18;000 feet without a clearance because they were unaware of the policy; which differs from U.S. procedures.
