Urban dictionary classifies Canuckistani as derogatory, but does not indicate the origin.
Most other references found in a brief web search seem to regard it in much the same humorous vein as Canuck or Frostback. There's even a few Canadians who have incorporated it into the titles for their websites, so I gather they are not deeply insuilted.
And the urban dictionary is probably run by a bunch of Yankees, so who cares?

Bog-Jumper - Many bogs in Ireland.
Bog-trotter - Abundance of bogs in Ireland.
Carrot Top - Hair color.
Cat-lick - Catholic.
Clover - Clovers are prevalent in Irish society.
Clown - Not used so much as a racial slur, however, the classic clown is based on a stereotyped image of Irish people: bushy red hair, a large red nose (from excessive drinking), and colorful clothes often with plaids, and often with a great many patches to represent that the Irish were poor and could not buy themselves new clothes. With excessive plaid is a Scottish variation.
Coal-Cracker - Many Irish immigrants mined coal.
Donkey - It was cheaper to hire an Irishman than a donkey in the Pennsylvania coal mining days of the 1800s.
Drunk - Irish are stereotypically drunks.

Hibe - Short for Hibernian (of, relating to, or characteristic of Ireland or the Irish).
Hillbilly - Ulster Scots who supported the Protestant King William of Orange at the Battle of the Boyne came to be known as "Billy Boys." The combination of "hill" and "billy" first came into use at this time. A large number of Appalachian settlers were Scotch-Irish, and the term arrived with them.
Leprechaun - From the well-known old Irish myth of the chubby green-clad gnome (what happens when you mix Catholicism with Paganism). Popularized in America by Lucky from the Lucky Charms cereal and St. Patrick's Day.
Leprecoon - Combination of Leprechaun and Coon for blacks of Irish descent.
Mackerel Snapper - It can be applied to any Catholic, Irish or otherwise. In the past, Catholics were forbidden from eating meat on Fridays.

Still observed in heavily-Catholic areas (they even have school/church fish-fry Fridays).

Plastic Paddy - Term used by the Irish describing those who grew up in the a foreign country (specifically the UK) and still identify as being Irish.
