They do occur in other systems, but Ottawa is experiencing an order of magnitude more incidents. A lot of this is OC Transpo's inexperience, running the slow and low volume Trillium line is very different than a metro line.
The other problem is LRTs use plug doors rather than sliding doors, so a door jam is more likely than on say a Montreal train.
The TTC, being far more experienced than us, had Bombardier uograded the new TTC streetcar doors from standard, expecting issues like this. They are more resistant to being forced open
It's hard to compare us to others as we are brand new to this. We're the first city in Canada or the US to join the metro club since the 80s. Recent LRTs in the states aren't running like ours, nor do any of them come close in ridership. The closest comparable is Seattle, but they started with a pair of 30 meter trains running at 10 minutes in rush hour, nowhere close to the levels of fault tolerence we need. The next city that will have a metro is Honolulu, it will be interesting to see how they fare.
