You can call them and ask. The Niagara crossings have specific rules about flagpoling, days, and times.
 
Niagara crossings only allow flagpoling Tues/Weds/Thurs and even then there are often reports here they have a quota of people they will process. You should still check with CBSA given the situation can obviously change

What time do you think it's best I go so that I can be processed without issue
 
I would recommend going to Windsor - The last time I checked, they allow 24/7 flag polling and there's a shuttle bus which takes you over to the US side and brings you back to the Canadian side. People have bad experiences with being turned away at Niagara falls
