        other
        in
        the

      The

      by
      
      
      Statutes
      of
      Canada,
      1963,
      chapter
      21,
      Section
      26(1),
      assented
      
      
      to
      December
      5,
      1963,
      and
      by
      virtue
      of
      subsection
      (2)
      thereof,
      
      
      subsection
      (2)
      of
      Section
      138A
      was
      made
      applicable
      to
      the
      1964
      
      
      and
      subsequent
      taxation
      years.
      
      
      
      
    
      The
      contention
      of
      counsel
      for
      the
      appellants
      was,
      as
      I
      understood
      
      
      it,
      that
      the
      authority
      conferred
      upon
      the
      Minister
      by
      Section
      
      
      138A
      (2)
      is
      a
      delegation
      of
      legislative
      power.
      He
      based
      this
      
      
      conclusion
      upon
      the
      circumstance
      that
      under
      the
      previously
      
      
      existing
      law,
      that
      is
      Section
      39
      of
      the
      
        Income
       
        Tax
       
        Act,
      
      as
      it
      
      
      previously
      read
      and
      still
      reads,
      the
      appellants
      were
      not
      associated
      
      
      corporations
      and
      in
      order
      to
      become
      associated
      and
      taxed
      
      
      accordingly
      that
      status
      had
      to
      be
      changed
      by
      the
      Minister’s
      
      
      exercise
      of
      the
      discretion
      conferred
      upon
      him
      by
      Section
      138A
      (2)
      
      
      which
      he
      did
      in
      1966
      applicable
      to
      the
      appellants’
      1964
      taxation
      
      
      years
      and
      assessed
      the
      appellants
      accordingly.
      He
      then
      referred
      
      
      to
      the
      well
      recognized
      rule
      of
      construction
      that
      statutes
      are
      not
      
      
      to
      be
      interpreted
      so
      as
      to
      have
      a
      retrospective
      operation,
      unless
      
      
      they
      contain
      clear
      and
      express
      words
      to
      that
      effect,
      or
      the
      object,
      
      
      subject
      matter,
      or
      context
      shows
      that
      such
      was
      their
      object
      and
      
      
      contended
      that
      the
      rule
      applicable
      to
      retroactive
      legislation
      
      
      enacted
      by
      Parliament
      should
      be
      applicable
      with
      equal,
      if
      not
      
      
      greater
      force,
      to
      the
      exercise
      of
      delegated
      legislative
      authority
      
      
      which
      is
      retroactive
      in
      its
      effect.
      
      
      
      
    
      Counsel
      for
      the
      appellants
      then
      referred
      to
      the
      use
      of
      the
      
      
      present
      tense
      of
      the
      verb
      ‘‘to
      be’’
      throughout
      Section
      138A
      (2)
      
      
      and
      Section
      138A(3)
      (b)
      (ii)
      as
      contrasted
      with
      the
      alternative
      
      
      use
      of
      the
      past
      and
      present
      tenses
      in
      Section
      138A(1)
      and
      Section
      
      
      138A(3)
      (b)
      (ii)
      and
      submitted
      that
      Section
      138A
      (2)
      does
      
      
      not
      give
      clear
      authority
      to
      the
      Minister
      to
      operate
      thereafter
      
      
      retroactively
      at
      his
      own
      free
      will
      and
      choice
      so
      to
      be
      able
      in
      1966
      
      
      to
      change
      the
      tax
      status
      of
      the
      appellants
      in
      1964,
      but
      rather
      
      
      that
      Parliament,
      by
      the
      careful
      employment
      of
      the
      present
      tense
      
      
      throughout
      Section
      138A(2)
      intended
      to
      authorize
      the
      Minister
      
      
      to
      make
      a
      direction
      thereunder
      only
      in
      the
      same
      year
      as
      that
      
      
      in
      respect
      of
      which
      he
      formed
      his
      opinion
      and
      gave
      his
      direction
      
      
      and
      not
      with
      respect
      to
      prior
      years.
      It
      was
      his
      contention
      that
      
      
      the
      use
      of
      the
      past
      tense
      would
      have
      been
      more
      appropriate
      to
      
      
      give
      retroactive
      effect.
      He
      added
      that
      the
      submission
      for
      which
      
      
      he
      contended
      would
      not
      unduly
      hamper
      the
      administration
      of
      
      
      the
      
        Income
       
        Tax
       
        Act
      
      because
      the
      Minister
      and
      his
      departmental
      
      
      officers
      have
      available
      to
      them
      information
      respecting
      corporations
      
      
      for
      previous
      years
      from
      which
      it
      can
      be
      ascertained
      whether
      
      
      the
      circumstances
      will
      persist
      into
      the
      current
      year
      and
      a
      direction
      
      
      could
      be
      made
      accordingly.
      He
      also
      added
      that
      the
      
        Income
      
        Tax
       
        Act
      
      contains
      provisions
      whereby
      investigations
      can
      be
      conducted
      
      
      or
      additional
      or
      supplementary
      information
      can
      be
      required
      
      
      during
      the
      currency
      of
      the
      taxation
      year.
      He
      had
      in
      mind
      
      
      Section
      126
      and
      the
      appropriate
      subsections
      thereof.
      
      
      
      
    
      The
      obvious
      purpose
      for
      the
      enactment
      of
      Section
      138A(2)
      is
      
      
      to
      provide
      a
      further
      basis
      for
      determining
      that
      two
      or
      more
      corporations
      
      
      are
      associated
      with
      each
      other
      in
      a
      taxation
      year
      and
      
      
      so
      subject
      to
      a
      higher
      rate
      of
      tax
      than
      if
      they
      were
      not
      associated.
      
      
      The
      method
      of
      determining
      whether
      corporations
      were
      associated
      
      
      which
      prevailed
      prior
      to
      the
      enactment
      of
      Section
      138A
      
      
      (2),
      and
      which
      still
      prevails
      as
      a
      method
      of
      so
      determining,
      is
      
      
      dependent
      upon
      control
      within
      the
      meaning
      of
      Section
      39
      which
      
      
      falls
      to
      be
      decided
      as
      a
      question
      of
      fact
      if
      and
      when
      the
      matter
      
      
      ultimately
      reaches
      the
      Court.
      
      
      
      
    
      Section
      138A
      (2)
      is
      a
      section
      which
      is
      intended
      to
      bring
      within
      
      
      the
      classification
      of
      associated
      corporations
      a
      class
      of
      corporations
      
      
      which
      under
      pre-existing
      law
      would
      be
      outside
      it
      and
      this
      
      
      is
      done
      by
      vesting
      in
      the
      Minister
      the
      right
      to
      make
      a
      discretionary
      
      
      determination
      upon
      being
      satisfied
      as
      to
      the
      existence
      
      
      of
      certain
      facts.
      
      
      
      
    
      I
      have
      no
      doubt
      that
      Section
      138A(2)
      is
      not
      retrospective
      
      
      legislation.
      It
      received
      assent
      on
      December
      5,
      1963
      and
      was
      
      
      specifically
      made
      applicable
      to
      the
      1964
      and
      subsequent
      taxation
      
      
      years.
      It
      does
      not
      purport
      to
      change
      the
      tax
      payable
      by
      the
      
      
      appellants
      in
      their
      1963
      and
      previous
      taxation
      years.
      That
      is
      
      
      the
      appellants’
      vested
      right.
      If
      an
      Act
      provides
      that
      as
      at
      a
      
      
      past
      date
      the
      law
      shall
      be
      taken
      to
      have
      been
      that
      which
      it
      was
      
      
      not
      then
      that
      Act
      would
      be
      retrospective.
      That
      is
      not
      the
      present
      
      
      case.
      Retrospective
      operation
      is
      another
      matter.
      Interference
      
      
      with
      existing
      rights
      is
      another.
      There
      is
      a
      presumption
      that
      an
      
      
      Act
      speaks
      only
      as
      to
      the
      future,
      but
      there
      is
      no
      corresponding
      
      
      presumption
      that
      an
      Act
      is
      not
      intended
      to
      affect
      existing
      rights.
      
      
      Most
      Acts
      of
      Parliament
      do
      just
      that.
      I
      do
      not
      think
      that
      the
      
      
      appellants
      are
      entitled
      to
      have
      their
      status
      as
      non-associated
      
      
      corporations
      under
      prior
      law
      preserved
      inviolate
      for
      the
      future
      
      
      when
      a
      subsequent
      and
      different
      law
      will
      be
      applicable
      to
      them.
      
      
      The
      legislation
      is,
      therefore,
      prospective.
      
      
      
      
    
      There
      is
      no
      question
      whatsoever
      that
      where
      the
      Minister
      is
      
      
      satisfied
      that
      when
      the
      circumstances
      contemplated
      by
      Section
      
      
      138A(2)
      subsist
      in
      the
      1964
      and
      subsequent
      taxation
      years
      he
      
      
      is
      vested
      with
      an
      absolute
      discretion
      to
      direct
      or
      not
      to
      direct
      
      
      that
      the
      corporations
      are
      deemed
      to
      be
      associated.
      If
      he
      so
      directs
      
      
      after
      the
      taxation
      year
      then
      certainly
      that
      direction
      is
      retroactive
      
      
      in
      its
      effect.
      
      
      
      
    
      The
      question
      to
      be
      determined
      is
      whether
      Parliament
      intended
      
      
      to
      authorize
      him
      to
      make
      such
      a
      determination.
      To
      answer
      this
      
      
      question
      I
      must
      consider
      the
      language
      used
      in
      the
      section
      and
      
      
      consider
      that
      language
      in
      the
      context
      of
      the
      Act
      for
      the
      purpose
      
      
      of
      deciding
      what
      is
      its
      fair
      meaning.
      
      
      
      
    
      The
      legislative
      scheme
      of
      the
      
        Income
       
        Tax
       
        Act
      
      is
      that
      taxes
      
      
      thereunder
      are
      imposed
      on
      a
      yearly
      basis.
      One
      of
      the
      two
      factors
      
      
      upon
      which
      the
      Minister
      must
      be
      satisfied
      in

      that
      one

      Clearly
      the

      determine
      the
      amount
      of
      tax
      payable
      by
      a
      particular

      the

      of
      income
      of

      the

      at
      some

      Under
      Section
      44
      of
      the
      
        Income
       
        Tax
       
        Act
      
      a
      corporation
      may
      file
      
      
      its
      return
      of
      income
      for
      a
      taxation
      year
      within

      months
      from
      
      
      the
      end
      of
      that
      year.
      Different
      corporations
      may
      have
      different
      
      
      taxation
      years.
      It
      is
      therefore
      logical
      to

      Parliament,
      
      
      being
      aware
      of
      such
      provisions
      in
      the
      
        Income
       
        Tax
       
        Act,
      
      
      
      must
      have
      contemplated
      the
      Minister
      ordinarily
      exercising
      his
      
      
      discretion
      after
      the
      conclusion
      of
      the
      relevant
      taxation
      years.
      
      
      
      
    
      In
      my
      opinion
      therefore
      the
      language
      of
      Section
      138A(2)
      
      
      clearly
      points
      to
      the
      legislative
      intent
      that
      the
      Minister
      in
      1964
      
      
      or
      subsequently,
      for
      any
      taxation
      year
      subsequent
      to
      a
      1963
      
      
      taxation
      year,
      if
      he
      is
      satisfied
      as
      to
      the
      state
      of
      facts
      contemplated
      
      
      by
      Section
      138A
      (2)
      for
      the
      year
      in
      question,
      can
      exercise
      
      
      the
      discretion
      vested
      in
      him
      prior
      to
      assessing
      or
      re-assessing.
      
      
      
      
    
      I
      would,
      therefore,
      answer
      the
      question
      posed
      in
      the
      Special
      
      
      Case
      for
      the
      opinion
      of
      the
      Court
      in
      the
      affirmative
      and
      dismiss
      
      
      the
      appeals
      with
      costs.
