I think we should look at the Interpretation Act, as that is what we must look at first. What does it say?
“security” means sufficient security, and “sureties” means sufficient sureties, and when those words are used one person is sufficient therefor, unless otherwise expressly required;
Now lets look at an Act governing the exchange of securities.
"security" includes
(a) a document, instrument or writing commonly known as a security,
(b) a document evidencing title to, or an interest in, the capital, assets, property, profits, earnings or royalties of a person,
(c) a document evidencing an option, subscription or other interest in or to a security,
(d) a bond, debenture, note or other evidence of indebtedness, share, stock, unit, unit certificate, participation certificate, certificate of share or interest, preorganization certificate or subscription other than
(i) a contract of insurance issued by an insurer, and
(ii) an evidence of deposit issued by a savings institution,
(e) an agreement under which the interest of the purchaser is valued, for the purposes of conversion or surrender, by reference to the value of a proportionate interest in a specified portfolio of assets, but does not include a contract issued by an insurer that provides for payment at maturity of an amount not less than 3/4 of the premiums paid by the purchaser for a benefit payable at maturity,
(f) an agreement providing that money received will be repaid or treated as a subscription to shares, stock, units or interests at the option of the recipient or of any person,
(g) a profit sharing agreement or certificate,
(h) a certificate of interest in an oil, natural gas or mining lease, claim or royalty voting trust certificate,
(i) an oil or natural gas royalty or lease or a fractional or other interest in either,
(j) a collateral trust certificate,
(k) an income or annuity contract, other than one made by an insurer,
(l) an investment contract,
(m) a document evidencing an interest in a scholarship or educational plan or trust,

an instrument that is a futures contract or an option but is not an exchange contract, or
(o) a permit under the Oil and Gas Activities Act,
whether or not any of the above relate to an issuer, but does not include an exchange contract;
Looks to me like the word 'security' means a financial instrument.
What does it mean to you?
