A commemorative ceremony to honour Canadians who served in the First World War will close off some major downtown roads on Friday.

The 11 a.m. ceremony at the National War Memorial and The Tomb of The Unknown Soldier, will honour WW I veterans, the last of whom — John "Jack" Babcock — passed away earlier this year at the age of 109.

The following street closures will be in effect from 8:45 a.m. to 12:30 p.m.:

  • Rideau-Wellington Street between MacKenzie Avenue-Sussex Drive and O'Connor Street; Queen Street between Metcalfe Street and Elgin Street;
  • Elgin Street (northbound and southbound sections) between Wellington Street and Albert Street.

The ceremony Friday also marks Vimy Ridge Day, which commemorates the battle won by Canadian soldiers during the conflict.
