Not as fixed heirs under the classical rules, but Canadian law treats an adopted child exactly as a biological one. The gap is bridged with a bequest.
The Canadian position
A legally adopted child inherits on intestacy and under a will identically to a biological child. There is no distinction in Canadian law.
The Islamic position
Classical fiqh preserves lineage, so an adopted child does not take a fixed share. Scholars commonly direct that they be provided for from the one third, and some recommend a lifetime gift instead.
This is a question worth putting to a scholar directly, because Canadian adoption is legally complete in a way the classical category was not.
We have not yet researched whether the four Sunni schools differ on this specific point, so we are not going to tell you either way. If your own case turns on it, put it to a scholar of your school.
Leaving an adopted child nothing invites both a family rupture and a dependant support claim. Provide deliberately.
