Canadian Climb and Descend Via Phraseology
In 2016, ICAO recommended that member states adopt standardized phraseology for departure (SID) and arrival (STAR) procedures in an effort to harmonize phraseology used by both air traffic control and pilots; however, these changes are not regulatory, and each member state must chose when, or even if, they plan to implement them.
In past years, there has been a significant difference between the phraseology used by US and Canadian controllers in regards to SID and STAR procedures. Owing to the recommendations of ICAO, beginning April 27, 2017, Canadian controllers will begin using "Climb/Descend Via" phraseology for all SID and STAR procedures which incorporate speed and altitude restrictions.
