Answer : Landscape architecture is different in Canada and the US. In Canada it would be more of a landscape architect as opposed to a garden designer or an interior designer.
In order to become one, you need to first have experience design with aspects that may include "hardscape", water features, space planning, site analysis, selecting plants for design concepts" particularly in times when we're looking at rising sea levels and global warming." Although there are many paths one can take towards becoming a Landscape Architect Canadian universities offer degrees in Landscape Architecture through application only. These degrees are typically 4-5 years long with courses including "mapping techniques", drafting methods and presentation skills.
