I understand, just saying because when I wanted to flagpole in my case, I also drove to Kingston to get it done. Reason being - Through a forum only, I figured out that for Niagara:
1. You have to go really early to get it done, sometimes they do not even entertain you if there are so many people, they send everyone back.
2. They work only limited hours, that too 1-3 weekdays. They do not work on weekends, so you might need to take a day off from work.
3. I have heard of cases where someone goes there for at least 2-3 times for flagpole, but they come back unsuccessful without a strong reason.
Rest, it all depends on what your preferences are, and your convenience.
Good luck
