Educated at Hellmuth Boy's College, London, he then proceeded to the Royal Military College of Canada, passing out in 1865. He served as an officer at Windsor, Ontario during the Fenian raids, earning a medal. Following this he entered his brother William's legal offices and was called to the Bar in 1869. Specializing in chancery and equity law, he went into practice with another brother, Edmund Meredith Q.C., a well-known criminal barrister, forming the London-based firm of Meredith & Meredith, subsequently Meredith, Judd & Meredith. He continued his career in London, during which time he took silk as a Queen's Counsel, until the Prime Minister, Sir John A. Macdonald appointed him a Judge of the Chancery Division of the High Court of Ontario in 1890, at Toronto. In the same year, he was also elected to the vice chancellorship of Ontario, a position he held until 1905. From 1905 to 1912, he was President of the High Court of the Supreme Court of Ontario. In 1905, he also served as a Judge at the Court of Appeal, where his frequent disagreements with his brothers William and Edmund earned him the nickname 'the dissenting judge'. In 1912, he succeeded his elder brother, William, as Chief Justice of the Court of Common Pleas, his final judicial post, retiring in 1930. He was sometime a director of the Ontario Investment Association.
Meredith was instrumental in the founding of The University of Western Ontario, at his hometown of London, Ontario. He served as the first Chancellor of the university and was Chairman of the Board of Governors between 1908 and 1914. He established the R.M. Meredith Society, still in operation today, to help fund under-privileged students.
Personality
He retired from the Bench at the age of 83, and moved back from Toronto to the home where he was born, on Talbot Street, London, Ontario. "A noted athlete in his youth, he preserved in his erect bearing and brisk step, great physical vigour and athletic energy, even after he had reached an advanced age." Like many of his brothers he had a great love of flowers and floriculture, and was at his happiest whiling away the hours in his extensive gardens on the Meredith's London estate. His obituary read, Chief Justice Meredith had a certain self-assurance and impatience with intellects less able than his own that sometimes brought him into sharp conflict with judicial colleagues, but he had a profound knowledge of law, and his ability and fairness earned him the respect of the Ontario Bar... his disposition was very kindly and friendly, and he was at all times a gentleman. In court he required the most rigorous etiquette, but his strict fairness and careful attention to details made him respected by all members of the Bar. In his earlier days he was a well-known figure in Toronto society, but on returning to London he lived in almost complete retirement. In 1901, he presented a chime of ten bells, cast in England, and the clock on the clocktower to St. Paul's Cathedral in memory of his parents. He was the best man at the wedding of his brother, Sir Vincent Meredith in 1888. He was unmarried, and died at the home his father had built in the early 1840s, and where he was born. He is buried at the Meredith plot in Woodland Cemetery, London. He left an estate of $235,598, having given much away to charitable causes during his lifetime. His portrait, and that of his brother Sir William Ralph Meredith, hangs in Osgoode Hall, Toronto.
