Got this from Wikipedia but just about summarizes which countries, ages and for how long are given to WHV grantees:
Canada
Citizens of Australia [6], Austria, Belgium, Chile, Czech Republic [7], Denmark, Estonia [8], France, Germany, Hong Kong, Ireland, Italy, Japan, Republic of Korea [9], Latvia, The Netherlands, New Zealand [10], Norway, Sweden, Switzerland, Taiwan, the United Kingdom and the US are eligible for a Canadian working holiday visa, so long as they fulfil certain criteria which are specific to each country.[1]
Citizens of Poland between the ages of 18 and 35 are eligible from 2009.[2] Canada has also signed an agreement with Spain.[3]
Citizens of Ukraine between the ages of 18 and 25 are eligible from 2010. There are no restriction for applicants status (non-students).[4]
Age limits are from 18-30 for most countries; 18-35 for citizens of Chile, Czech Republic, Denmark, France, Germany, Italy, Ireland and Switzerland. Some countries' programs specify that the applicant must be a full-time student; others do not, and some have separate programmes for students and non-students.
The type of work allowed and the maximum duration of stay depends on the applicant's country of residence.
