OK. I think it's necessary for me to share my personal experience with you guys because in this thread, I haven't seen any applicant who was required to submit the Letter of Good Conduct from the original country.
A brieft instruction of myself: I came to Canada from northern China on December 12th 2014. I live in Vancouver, BC. I was required to provide my Letter of Good Conduct (no crime record) under the Firearm Act. Chinese is my 1st launguage for sure, and English is 2nd. I can't speak French at all.
March 26th 2017: All relevant courses and exams finished by Silvercore in New Westminster, BC. Got the score paper as well. In BC, we don't need the stamped test results like ON.
July 15th 2018: Mailed my application to NB via snail mail (cheapest option from Canada Post). The reason why I waited for 16 months after the exams was because my old Letter of Good Conduct expired, had to get a new one.
July 20th 2018: NB received.
August 27th 2018: Credit card was charged, and application status shows up online.
September 3rd 2018: The original document of Letter of Good Conduct was sent back from NB. They sliced it into 4 pieces in order to fit their envelope.
Since then, I have called NB, BC, NB. Asked them whether my documents were all fine, if we could conduct the interview now. They didn't answer my questions, but indicated no interview requested.
September 28th 2018: Licence issued. Neither my references nor myself was interviewed.
October 5th 2018: Licence in my hand.
Total process time from their receipt to approval: 70 days.
***Bonus Story***
October 6th 2018: Got my 1st firearm in my life--Soviet Union SKS from a local gun shop. Carried it in a cardboard box, and walked 3.7km home. I called Transit police prior to my purchase, asked them whether it's OK to trasport it via #19 bus. The police didn't directly deny me, but they didn't want me to do so. Yes, I NEVER drive.
If you have any questions, feel free to ask. I am now working on my English skills for immigration purproses. When I have time, I will absolutely make a Youtube video of my licence application specifically toward Chinese potiential gun owners.
