Yes they do, but they tend to be harder to find. Since the Bank of Canada no longer uses "stars" anymore. On the Canadian Journey series the only way to find a replacement note is to go through uncirculated bricks and find notes that do not run consecutively with the other serial number in the block. Once circulated it is difficult to tell if they are regular or replacement. They can also have a different letter prefix then the rest of the bills.
There are two ways printers deal with notes damaged in the printing process. One is called the replacement method where a different series of notes are printed and inserted into the finished product in place of the damaged notes. These will usually be identified usually by a unique identifier in the serial number such as stars, crosses, different prefixes, etc. US MPC replacements do not have a suffix letter in the serial number. JIM notes for the Philippines were identified with a leading number 1 in the serial number. Japanese military notes for China have a leading number 9 in the six digit serial number notes and a leading 1 in the seven digit notes. The other system is the make up system. In the make up system, the replacement note is given the same serial number as the replaced note. This system is most frequently used by private contractors. The make up system hides how many notes were replaced. Too many replacements may not be appealing to the customer. Try finding a replacement on a series printed by ABNC. Small size US National currency used a make up system. The serial numbers on replacements were applied by hand and can be identified with a trained eye because they are often misaligned. The replacement system was traditionally more efficient for the printer from a time stand point than the make up system. Advances in printing technology may have closed that gap
But what Canada now uses is a third system. When they catch a defective note, they just pull it out, so the serial numbering sequence just skips a number. So let's say note number 47 had a printing error; then the first pack of notes will have 1 through 46 and then 48 through 101, and the second pack will start at 102 instead of 101.... Every 10,000 notes or so, they "top up" a pack with a bunch of extra notes with random unrelated serials, to make up for all the error notes they've removed lately. But these aren't star/replacement notes, with special distinctive serials; they're just any old notes. Unless you yourself find them stuffed in at the end of a brand-new pack of notes, you have no way of knowing that these particular serials were used as top-up notes.... Under this system, there's no longer a close connection between the number of notes printed and the serial range used--you can't just subtract the low serial from the high serial to figure out how many notes were printed. Drove the collectors a bit batty when the system was first introduced, really....
Well you could always collect the bills where the serial numbers and letters spell a word. got onethat has ARE ####### on it lol
