ABSTRACT: This paper presents geotechnical investigation results conducted in the glacial till deposits in relation with a light rail transit project in Toronto, Ontario. The ranges of soil parameters including unit weight, water content, strength, modulus, consolidation parameters and shear wave velocity are provided. Statistical analyses of soil parameters are conducted, where available. Possible correlations between SPT N value and pressuremeter modulus and soil friction angle are discussed. In additional, the distribution of boulders and cobbles in the glacial till deposits is also discussed through the observation of a shaft excavation for a tunnel project in Markham, Ontario.

RÉSUMÉ: à Toronto (Ontario). Les paramètres de sol, incluant le poids spécifique, la teneur en eau, la résistance, le module, les paramètres de consolidation et la vitesse des ondes de cisaillement sont fournis. Des analyses statistiques sur les différents paramètres du sol ont été conduites. Des corrélationpressiomètre sont discutées. De plus, la distribution de graviers est également discutée suite à des observations dans
