I received a letter of termination in the mail while I'm off on sick leave with no explanation as to why, can they so such a thing?

Generally an employer can terminate an employee at any time, on a without cause basis, such that you are paid your termination entitlements. However, if you are on a medical leave from work, they have a duty to reinstate you to your position or to a comparable position, unless your position has been validly eliminated. As such, if terminated while on a sick leave, not only would you be owed your termination entitlements, you are likely also owed Human Rights damages as a result of the employer's breach of the Ontario Human Rights Code.
