Grimes in Kitchener became Phonola then Dominion Electrohome. Their radios may be listed under Phonola or Grimes Phonola. The last patent date on your radio is 1926, that is probably the age of your radio. The Radio College of Canada (RCC) listings I have start in 1927 and do not show your radio.

Perhaps someone with earlier data may be able to help.
