Editing Arbor Day (section)

===Canada===
The day was founded by Sir [[George William Ross]], later the premier of Ontario, when he was minister of education in Ontario (1883–1899). According to the Ontario Teachers' Manuals "History of Education" (1915), Ross established both Arbour Day and Empire Day—"the former to give the school children an interest in making and keeping the school grounds attractive, and the latter to inspire the children with a spirit of patriotism" (p.&nbsp;222). This predates the claimed founding of the day by Don Clark of Schomberg, Ontario for his wife Margret Clark in 1906. In Canada, [[National forest week|National Forest Week]] is the last full week of September, and National Tree Day (Maple Leaf Day) falls on the Wednesday of that week.<ref>{{Cite web |url=http://www.canadianforestry.com/wp/national-forest-week/. |title=The Canadian Forestry Association.
