There were 11,532,784 nickels minted in Canada in 1944. The coin (KM#40a), with a diameter of 21.2mm, is 4.400 grams of chrome plated steel. It is worth (according to the Standard Catalog of World Coins) about US$0.35 in Fine condition, US$0.90 is Extremely Fine, US$2.00 in Uncirculated, and US$7.00 in Brilliant Uncirculated (MS-63). Note that there were also about 8,000 nickels minted in 1944 out of Tombac, a material similar to brass. Only one is currently known, and it is obviously quite valuable.

Canadian money does not actually have a nickel. They have what is called a five cent piece. A 2002 Canadian 5¢ piece is only worth face value.
Its face value is 5 cents, but the melt value of a 1955-1981 Canadian nickel is $0.09 so the melt value is 4 cents more than the face value of the coin5 cents. It's not rare, and many are still in circulation.
It's worth about a dollar, just for the silver.
They're both only worth face value.
Canadian nickels (1922 and later) never contained silver. A 1967 Centennial nickel is made of 99.9% nickel and is worth about 15 cents in above-average condition.
If it's been in circulation, maybe face value to 10 cents.
