Hello how may I help you? I have a question about the city of Montreal. What did you want to know? Can you tell me the name of the river Montreal is on? Montreal lies at one end of the Saint Lawrence Seaway. Is there a river that runs through the city? Yes, the Saint Lawrence Seaway. Oh, I didn't know that was the name of a river. Silly me! Thanks for your information! Canada is weird. You are welcome. Anything else? No I think you have answered my question. Thank you! You're welcome
