===Mid-life refit and fate===
The 1964 Navy estimates called for the major refit of ''Bonaventure'' in order to extend the aircraft carrier's service life.{{sfn|Milner|2010|p=247}} While the Canadian Naval Board planned the carrier's upcoming refit, ''Bonaventure'' participated in the naval exercise [[Gooey Duck]] which included training off [[Bermuda]] in January and in February, sailed to the [[Mediterranean Sea]]. While there, ''Bonaventure'' was recalled to Canada to embark troops from the Canadian [[Royal 22nd Regiment]] for service in a [[United Nations]] peacekeeping venture. Called Operation Snow Goose, 95 soldiers, 54 vehicles and 400 tons of stores were loaded aboard the aircraft carrier and the ship disembarked them at [[Famagusta]], Cyprus on 30 March.  ''Bonaventure'' then returned to Canada before sailing to [[Norfolk, Virginia]], for trials with the [[A-4 Skyhawk]], a possible replacement for the Banshee. However, due to financial considerations, the Skyhawk was not purchased. In December, ''Bonaventure'' began sea trials with the Sea King helicopter.{{sfn|Hobbs|2013|pp=337–338}}

In January 1965, ''Bonaventure''{{'}}s air group was composed of VS 880 (Tracker), HS 50 (Sea King), an HO4S plane guard from HU 21 squadron and a COD Tracker from VU 32 squadron. From February to March 1965, ''Bonaventure'' took part in naval exercises and in May, visited the United Kingdom.{{sfn|Hobbs|2013|p=338}} On 2 April 1965, Captain [[Henry Porter (Canadian admiral)|Henry Porter]] became the commanding officer of the aircraft carrier.{{sfn|Macpherson|Barrie|2002|p=237}} In June, ''Bonaventure'' visited the Joint Anti-Submarine School at [[Derry|Londonderry]] and took part in joint operations in the [[Southwest Approaches]] with {{HMS|Ark Royal|R09|6}} and HNLMS ''Karel Doorman''. The following year in January, ''Bonaventure'', along with six escorts, took part in the largest Canadian naval activity in the Caribbean Sea and South American waters. During the exercise, the ship visited [[Rio de Janeiro]] in February and in March, returned to Halifax.{{sfn|Hobbs|2013|p=338}}

Beginning in April 1966, the carrier began a mid-life refit at [[Davie Shipbuilding]] in [[Lauzon, Quebec]]. The initial estimate for the refit was $8 million. However, during the refit, numerous issues with the ship, which had been present since construction, were found and led to cost overruns and delays. In the end, the refit took 18 months and cost $17 million, both behind schedule and well over budget. The refit was complete in August 1967.{{sfn|Milner|2010|pp=259–260}} During her refit, Captain A. T. Brice became the ship's commanding officer on 1 August 1966. ''Bonaventure'' rejoined the fleet in November 1967 with a new commanding officer, Captain R. H. Falls, who had taken command on 21 November 1966.{{sfn|Hobbs|2013|p=338}}{{sfn|Macpherson|Barrie|2002|p=237}}

Following the 1968 [[Unification of the Canadian Forces]], the Royal Canadian Navy ceased to exist and ''Bonaventure'' and naval aviation were merged with the rest of the Canadian Armed Forces, with naval aviation no longer under the jurisdiction of the navy. In February 1968, ''Bonaventure'' took part in a naval exercise in which a Sea King ditched into the sea. The crew were recovered alive and the helicopter was salvaged. In March, the ship visited [[New Orleans]], Louisiana, before spending the next two months in military exercises. 1969 was spent training with the United States Navy and participating in the naval exercise Peace Keeper off [[Ireland]].{{sfn|Hobbs|2013|p=338}} On 9 April 1969, Captain J. M. Cutts became the senior officer aboard the aircraft carrier.{{sfn|Macpherson|Barrie|2002|p=237}} ''Bonaventure'' visited [[Portsmouth]] before sailing to Canada on 22 October 1969. As the Canadian military sought to cut spending, ''Bonaventure'' was deemed surplus and the last night deck landing took place on 28 October, followed by a visit to [[Boston]], Massachusetts, before the last deck landing aboard ''Bonaventure'' took place on 12 December 1969.{{sfn|Hobbs|2013|p=338}}{{sfn|Milner|2010|p=264}}

A few last missions were left for ''Bonaventure''. On 9 January 1970, Captain H. W. Vondette became the final commanding officer of ''Bonaventure''.{{sfn|Macpherson|Barrie|2002|p=237}} In January 1970, the aircraft carrier (minus her aircraft) was sent to carry troops of the Royal 22nd Regiment to [[Jamaica]] for training exercises. In February, ''Bonaventure'' was used as a [[replenishment oiler]] to replenish the fuel stores of [[frigate]]s taking part in the Exercise Maple Spring. During this operation, ''Bonaventure'' had six Sea Kings of HS 50 aboard. In April the ship was sent to recover Canadian forces from [[Narvik]], Norway, after a military exercise and made a final visit to Portsmouth on the way back to Canada.{{sfn|Hobbs|2013|p=339}}

''Bonaventure'' was [[Ship commissioning#Ship decommissioning|decommissioned]] at HMC Dockyard in Halifax on 3 July 1970, and sold for disposal.{{sfn|Beaver|1982|p=119}}<ref>{{cite news |title=Bonaventure ends long career today |work=Halifax Chronicle-Herald |date=3 July 1970 |page=16}}</ref> During the component recovery process, parts from ''Bonaventure''{{'s}} steam catapult were used to undertake repairs to the catapult of her sister ship, {{HMAS|Melbourne|R21|6}} of the [[Royal Australian Navy]].{{sfn|Hall|1982|p=213}} The vessel was purchased by Tung Chen S Steel Company of [[Taiwan]] for scrap and [[Ship breaking|broken up]] in 1971.{{sfn|Hobbs|2013|p=339}}
