Shared with you what I know. In BC, family having autism child can get the financial aid about $20000 a year if child under 6 yrs, and around 6000 with child from 6-18 years. Also family is eligible to receive therapy services at centre for child development.
Please contact BC children hospital for more details, I believe they can book a Mandarin interpreter if you need :
