Leonard Nimoy fans have been turning the face on a Canadian bank note into his Star Trek character, as a tribute to the actor who died last week.

To 'Spock' the $5 bills, Canadians have been drawing the iconic slanted eyebrows and pointed ears onto the original image of Sir Wilfrid Laurier.

Although there is no law against writing on the notes, it is "strongly objected to" by the Bank of Canada.

People are still been sharing their "Spock" drawings on Twitter.

Even with "Spock" on the note, it is still legal tender, Canada Money Tracker claims. However, the Bank of Canada says it can limit the life of a note and replacing them costs the tax payer money.

The Bank of Canada has yet to respond to Newsbeat's request for a comment.

Sir Wilfrid Laurier was a former Prime Minister of Canada and appears on the old paper bank notes. The newer polymer notes also feature his image, but people are finding it harder to "Spock" this one.

Other tributes to Leonard Nimoy have also been dominating social media.

Nasa astronaut Terry W Virts gave the Vulcan salute from the International Space Station looking down at the Earth.

His Star Trek co-star William Shatner has been criticised for not attending his funeral over the weekend.

Shatner says he was attending a charity event in Florida and would not make it back to California in time to make the service.

He held a Twitter chat, in which he answered questions and shared his memories of Nimoy with their fans.
