The popular horticulture exhibit that took over Jacques-Cartier Park in Gatineau last year for Canada 150 celebrations will be back in 2018 — but you’ll have to pay. The Quebec and federal governments announced that the exhibit — known last year as MosaïCanada 150, and run by Mosaïcultures Internationales de Montréal — will return June 24 to Oct. 15, lasting one month longer than last year.
