Both documents are written statements of fact that you swear or declare to be true. The difference is mostly where they are used, who can take them and how they are worded. Using the wrong one can mean doing the job twice.
An affidavit is a statement of facts that you swear or affirm to be true. It is typically used as evidence in court or before a tribunal, for example in a motion or a hearing. It is divided into numbered paragraphs, signed by you, and followed by the commissioner's jurat, which says when, where and before whom it was sworn. Exhibits, such as documents, are attached and marked.
A statutory declaration is a written statement that you declare to be true, under a federal law, the Canada Evidence Act. It is used for things such as proving a name change, confirming a relationship, declaring that a document was lost or confirming facts for an agency or a company. It does not require an oath, but it carries serious consequences if it is false.
You can swear an oath, or you can make a solemn affirmation instead. You can choose which suits your beliefs.
Remote commissioning is possible in many circumstances. Ask the recipient whether it accepts it.
