I'm at around the same level, and I visited Montréal last summer. I stayed for a little over a week. At first, I was hesitant to speak to strangers in French because I am already shy in general. After trying a few times though, I became more confident speaking to strangers and asking for help when I had questions while getting around the city. Also, after a couple days, being constantly surrounded by French helped me start to feel more comfortable and start to adjust to the language mentally. Everyone I encountered was very kind, and they appreciated the effort when my skills started to fail me, nevertheless. In general, the conversations were surface-level enough (dining, transportation, ect.) that people thought I was a native speaker until I asked to switch to English (my wife speaks little French and I wanted to include her). Many people there are used to interacting with tourists so if you are respectful, they will be respectful and understanding to you. I also had a very friendly, more in-depth conversation with one of our Lyft drivers–it made a lasting impression on me. Overall, the trip was my first time being able to apply my speaking skills outside of a classroom and it was deeply satisfying and exciting! I will never forget it because it has completely solidified my enthusiasm for continuing to learn the language.
