No. A registry records that a will exists and where it is kept. Validity is a separate question, governed entirely by your province's formal requirements.
The Canadian position
A will is valid if it meets provincial requirements for writing, signature and witnessing. Registration adds nothing to that.
What registration does is solve the findability problem, which is a different and very real failure mode.
The Islamic position
The religious requirement is that the wasiyyah be documented and available. Registration serves that directly, without touching the question of legal form.
The four Sunni schools are not recorded as differing materially on this point in the sources reviewed. Where your own case turns on it, put it to a scholar of your school.
This is legal information only. For advice on your own circumstances, speak to a lawyer.
