Before 1953 Canada minted regular strike & specimen proof coins. A specimen proof is double struck but usually not as lusterous as an USA proof coin.
In 1953 Canada issued proof like sets. Proof like coins are lusterous better single strike coins.
The first Canada 1953 & some 1954 used a No strap design. All other Queen Elizabeth coins have strap design.
NGC and ANACS Proof Likes require a stronger proof like coin reflection.
The test used is: Can newsprint be read from the reflection on a coin.
I did not see any NGC 1953 Canada Proof Like coins offered by any dealers.
I previously submitted a 1953 No strap Canada Proof Like set to NGC to try to get a proof like. All of these coins returned as MS grades.
For the 1953 No strap dime only 3 NGC proof likes are known! 1 65, 1 64, 1 62.
I saw one offered with no bids. I emailed & purchased the pl64 no strap 1953 dime.
