One of the most noticeable differences between Canadian and American spellings is the use of “y” as the speller for both “yes” and “you”. Canadians use “ie” while Americans use “y’all”. Canadians also use the letter “h” to spell the word “help”, while Americans use “help”.
Canadians also tend to spell words ending in -our with a u, such as tour instead of tour. Americans spell these words with an o, such as tour.
Another difference between Canadian and American spellings is the use of double letters. For example, Canadians typically spell the word “antidisestablishmentarianism” with two a’s instead of one. Americans typically spell it with one a.
Canadian spelling also tends to include more French loanwords, while American spelling tends to omit them. For example, the word poutine is spelled poutine in Canada but pho in America.
While there are still many differences between Canadian and American spelling, these differences are gradually diminishing as more and more people adopt American spelling habits. This is likely due to the increasing popularity of English as a second language in both countries.
As more people learn to spell correctly, these differences will gradually disappear.
