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.
These coins were struck in steel to free up nickel for the war effort. They are worth about 20 cents if worn, up to maybe $1.50 in XF condition.

Five cents
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.
