Mr. Fraser, section 43 in part VII of the Official Languages Act states:
(d) encourage and assist provincial governments to support the development of English and French linguistic minority communities generally and, in particular, to offer provincial and municipal services in both English and French and to provide opportunities for members of English or French linguistic minority communities to be educated in their own language;
The government is responsible for transferring funding to the provinces. You say that it is not part of your mandate to verify whether the money goes to the right place. You also said that officials and ministers had said they used that funding for other purposes.
What are our commissioner's powers? If you are unable to investigate in the province, you could at least do so in the departments in order to see whether there is any accountability.
