This first picture I was able to ID by zooming in on the water tower and finding “Moirs Limited Chocolates Bread Biscuits”. Google quickly directed me to Halifax, Nova Scotia. I then found a Facebook link to old photographs of Halifax and then the following link which confirmed this was Halifax.
Here is a link to a photo of the old town clock at the left in this picture.

This next photo is a group shot of finely dressed people in front of "Lord Construction" "Work and Win Plant". Judging by the car and Work and Win slogan, I imagine this was taken during World War I. I did find a reference to a Lord Construction Company in Providence, Rhode Island that equipped/outfitted ships for the Emergency Fleet Corporation which was in operation from 1917 to 1920 to support the war effort. Check out the shiny shoes and the nice watch chain.
The last one I need some help with. It appears to be a BIG mock up of a World War I ship. Look at how many people are working on it. There is a subway entrance in the foreground. This was probably a set for a "Liberty War Bond" drive during WWI. Do you agree? Any ideas as to what city?
Followup: Brett Payne nailed the answer immediately after I posted the picture. Here is the link he directed me to:
