How to sign the book of condolences for Queen Elizabeth ll

Canadians have the opportunity to pay tribute to Queen Elizabeth ll in a book of condolences.

Starting today, people have the choice of signing the book in person at Rideau Hall in Ottawa between 9 a.m. and 7 p.m. or online.

Governor General Mary Simon signed the book Thursday evening before it was made available to the public.

Simon says people will be sharing words of remembrance about the Queen in numerous languages worldwide.

To honour the Queen, the Senate of Canada Building and the Peace Tower in Ottawa will be lit up in royal blue over the coming days.

The CN Tower in Toronto went dark Thursday night in her memory.
