The Act was first introduced by the late Senator
Mike Forrestall of Nova Scotia as a Private Member's Bill (S-21) in 2000. It was brought it forward three more times, as S-7, then as S-14, then as S-41 which was given Third Reading by the Senate on March 23, 2005. The House of Commons debated the bill in June 2005 in Second Reading and referred it to the Standing Committee on the Environment and Sustainable Development for clause-by-clause review. The bill died on the
Order Paper when the federal election of January 2006 was called. Following the death of Senator Forrestall in June 2006, the bill was re-introduced as Bill-S220 in October 2006 by Senator
Pat Carney of British Columbia. The Bill was given Third Reading and passed by the Senate on December 14, 2006. The bill was first sponsored in the House of Commons by Conservative Member of Parliament
Gerald Keddy. It passed Second Reading on June 13, 2007, and was scheduled to be reviewed by the House of Commons Fisheries Committee in October 2007 before Third and Final Reading. However, the announcement on September 4 that Parliament would be prorogued in October put the bill back to the Senate where on October 30 Pat Carney re-introduced it as Bill S-215. The Bill passed Third Reading in the Senate on December 13, 2007, and was re-introduced in the House of Commons by Conservative Member of Parliament
Larry Miller where it passed 2nd Reading on March 11, 2008. The bill was referred to committee where an amendment were made to define lighthouse structures and limit the act to federally owned lighthouses. The Third and final Commons vote was made on May 1, 2008, followed by a Senate vote to approve the amendment which the bill passed on May 8.
Royal Assent was given on May 29, 2008. Other MPs such as
Catherine Bell from British Columbia welcomed an initiative to preserving a national landmark as a healthy alternative to contentious partisan issues of a minority Parliament. The only formal opposition was voiced by a Bloc Quebecois MP
Raynald Blais who said he could not support the bill because it might mask federal neglect of other DFO responsibilities. In addition to regional lighthouse advocates such as the
Nova Scotia Lighthouse Preservation Society, the
Heritage Canada Foundation was a consistent supporter noting that lighthouses need special protection because of the lack of federal legislation for any federal buildings. Despite the broad public support for the bill, some federal departmental staff initially opposed the bill suggesting it could cost up to $384 million to upgrade all of Canada's lighthouses to heritage standards. Supporters of the bill called these numbers inflated, pointing out that it assumes that every piece of navigational equipment in the country, including hundreds of steel towers and floating buoys, would be designated whereas even the strongest proponents only anticipate the nomination of a select number of landmark lighthouses. They also noted that the bill leaves control of the number of designations, and any associated, costs, with the minister. ==Implementation and controversy==
