You are not making any sense? Do you mean that there is a Vancouver Olympics Quarter only minted in 2010 and that yours says 2007? Show both sides.
Canada issues the regular quarter design in addition to commemoratives in the vast majority of years. Your coin is not an error.
The mintage on the 2007-L Caribou quarter is 275 million, the mintage on each Olympic design in 2007 is only 22 million. You're more than twice as likely to find a caribou as you are to find all 5 Olympic designs from the year combined.
The 2007 quarter in question was struck as a commemorative issue for the forthcoming XXI winter olympics that would take place in Vancouver 2010
