Timiskaming
Timiskaming is a word from the Algonquin Temikami or Temikaming, from tim meaning "deep" and kami meaning "open waters". Alternate spellings include: Temiskaming, Témiscaming, Témiscamingue. The word Temagami comes from the same root.

Controversy exists over the spelling of this word.  A movement to change the spelling of the District of Timiskaming to Temiskaming (an e instead of an i) cites a typographical error by a government official, but the act of parliament that led to the name change granted this official authority to correct the spelling.  What he considered to be a spelling correction, some people today call a spelling mistake.

The spelling controversy goes back to the 18th century.  English maps from that century show the spelling of the lake as Temiscamin, Temescaming, Temiscaming, Timiscaming, and Temiscamino, with Temiscaming being the most common.  Spelling of the name of the aboriginal tribe presented even more alternatives.  In all cases, though, there is no k.  The 21st Century has inherited a debate from the 18th Century.
