To begin with here is a cancel from Brockville, Ontario which is named after Sir Isacc Brock. I used the General Sir Isacc Brock Stamp issued this year for the cover.
Here is the cancel from Liverpool, Nova Scotia. I wrote a article about it and you can find it here.
Here is the pictorial cancel from Brock, Saskatchewan. It is another town named after General Brock.
I had a bunch of 59¢ stamps from 2011 Parks Canada centennial issue so I am using them to get cancels from areas that are related to the Parks Service. First is Banff, Alberta.
Next one is from Stirling Alberta.
This one is from Orion, Alberta, it would be good for a number of thematic/topical collections
Here is one from Victoria, Prince Edward Island. I used the Year of the Dragon stamps issued in 2012.
