He signed for Primera club Rampla Juniors ahead of the 2012 Clausura, at the end of which a 7–1 defeat at home to Peñarol confirmed their relegation.[8] Canosa left for Argentina, to join Olimpo de Bahía Blanca on loan for the season. However, he could not force his way into an already well-populated defence, the loan was cancelled, and Canosa returned to Rampla Juniors for the 2013 Clausura.[9][10][11] He continued to play for Rampla Juniors for the rest of 2013, before finishing the season with another Segunda División club, Villa Teresa.[6][12]
In August 2014, Canosa returned to the Primera with Cerro.[13] He was a regular starter as Cerro struggled in the first half of the season but improved in the second to avoid relegation.[6][14]
He signed for América de Cali of the Colombian Primera B in June 2015. He said he was keen to bring his good aerial play, ability to organise a defence, and leadership qualities to a team anxious for promotion.[15] He was a regular starter, helping América qualify for the promotion phase, but they came second in their group so failed to reach the final,[6][16] and Canosa was released.[17] His next port of call was Manta, in Ecuador, where he joined Serie A club Delfín.[18] He had played seven league matches[6] when a major earthquake struck the area in April 2016. More than 200 residents of the city were killed and thousands made homeless.[19][20] The frightening experience he went through, and concern for his wife and young baby as aftershocks continued, caused him to request and the club to grant the immediate cancellation of his contract so that he could return home.[21][22]
