I just came out from ICBC (the DMV of British Columbia, Canada) and had the exact same issue. I don't know if this only happens with people from NJ, but it was somewhat comforting to find this post knowing that I'm not alone.
I read through the ICBC official website before I came to Canada. The website said I need to provide two years of driving history. For example, a driver license report. So I went on the NJMVC website and got the certified driving history report. Yes, I did realize the different wording, one with “license” the other one without. But I didn’t think that would be a problem because a) they are different countries so different in wordings are understandable, and b) that’s the only thing NJMVC has to offer.
Unfortunately that report did not show the date of when I first got my license. And that date was what ICBC was looking for. I also didn't think it would be an issue since (unfortunately) I got my first ticket in 2015, so it would at least count for a good 7 years (2015-2022) of driving experience. Well, seems like that's not the case.
I was told "you could drive and get a ticket without having a license". They couldn't count that as driving experience because the paper did not show when did I first got my license. I had 10+ years of driving experience, but I just recently renewed my license, so on the NJ license it looks like I've only had a license for less than a year.
So I asked the lady "you do realize people can have a license but do not drive right?". I don't understand how does having a license equal to having driving experience? Honestly, even if I was driving without a license, I was driving, and that's driving experience. Of course the lady had to talk to her supervisor and came back with a "no". Then she suggested me to go back and try to find my previous licenses. So the only thing I can say to her was to suggest they change the wording on their website. What they are looking for was not "two years of driving history", but instead "two years of in possession of a license".
Anyways, I do hope people from NJ who's looking to get a Canadian driver's license read this post. I wish I had read this before I came. The only tip for people who recently renewed your license -- go dig in your drawer and find those expired licenses!
